A novel composite and functional micro-nanometer particle is designed by the hydrolysis of aluminum isopropoxide on the surface of ammonium polyphosphate (APP) to prepare surface nanostructured ammonium polyphosphate (NSAPP). NSAPP is characterized by XPS, XRF, SEM, water solubility tests, and TGA. Results indicate that nanosized aluminum hydroxide is deposited on the surface of NSAPP, which enhanced its water resistance and thermostability. Then, APP and NSAPP coupled with dipentaerythritol (DPER) is used for the flame retardant of polypropylene (PP). The limiting oxygen index value of the PP/DPER/NSAPP composite is higher than that of PP/DPER/APP. Besides, the UL 94 vertical burning test of PP/DPER/NSAPP composites can reach the V-0 rating easily. According to the study of the combustion behavior of FR-PP composites, NSAPP contributes to form a dense and multi-layered char in the combustion process. Thus, such an intumescent char with a ceramic-like, continuous, and dense structure over the PP matrix protects the underlying matrix and enhances the thermal stability of the condensed phase, thereby improving the flame retardant performance of FR-PP. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Application In Synthesis of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).

Mechanism of boron carbide particles improving the wear resistance of UHMWPE: Structure-property relationship was written by Liu, Zhipeng;Du, Yue;Ma, Haixia;Li, Jiangshan;Zhang, Xixiang;Zhu, Enci;Shi, Chunliang;Zhu, Zhihua;Zhao, Shicheng. And the article was included in Polymer in 2022.HPLC of Formula: 6683-19-8 This article mentions the following:

Inorganic particles are often used to enhance the wear resistance of UHMWPE, but the mechanism of the “enhancement effect” of inorganic particles improving the wear resistance of UHMWPE is ambiguous. In this paper, boron carbide particles(B₄C) were used to improve the wear resistance of UHMWPE, it was found that the wear resistance of UHMWPE was increased by up to 46% with appropriate filler loading of B₄C. Subsequently, the mechanism of B₄C improving the wear resistance of UHMWPE was studied and illustrated from the perspective of structure-property relationship. The B₄C particles act as exotic entanglement points, forming an entanglement network of particle-coupling agent-matrix, improving the degree of entanglement of mol. chains in the amorphous region of UHMWPE, thus improving the shear resistance of the matrix and reducing the structure damage caused by strong shearing during friction. Meanwhile, the highly entangled mol. chains prevented the transition of the interphase to the crystalline region, thus increasing the content of the interphase of UHMWPE and consequently alleviating the structural damage during the friction. Furthermore, B₄C particles played the role of load bearing, which enhanced the compression resistance of UHMWPE then reduced the structure damage caused by compression in the normal upward during friction. This paper could be helpful to better understand the role of fillers on the wear resistance of UHMWPE and provide theor. guidance to improve the wear resistance of UHMWPE and other materials. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8HPLC of Formula: 6683-19-8).

Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water.

Preparation the composite with high toughness and strength by recycled cyclic olefin copolymer was written by Sun, Ming Yang;Liu, Wen Chuan;Wu, Yuan Sheng;Qian, Hao. And the article was included in Polymer Engineering & Science in 2022.SDS of cas: 6683-19-8 This article mentions the following:

At present, it is of great significance to develop an effective method of recycling cyclic olefin copolymers (rCOC) due to its increasing application. But, its poor toughness is still an important difficulty to limit its effective recycling. In this article, we introduced PA6 into the POE-g-MAH/rCOC composites. Because of the good compatibility of POE-g-MAH between PA6 and rCOC, it just led to an overall improvement in mech. properties of PA6/POE-g-MAH/rCOC (45/15/40) composites. Its tensile strength reached 42.3 MPa, which was more than 41.9% compared with that of POE-g-MAH/rCOC composites. Its notched impact strength was 11.7 kJ/m², which was higher than 875.0% compared with rCOC. Furthermore, the component of PA6 was wrapped by nonpolar rCOC and POE-g-MAH, resulting in a low water absorption rate (1.0%). So, the strength of the composites only dropped a little after water adsorption. In summary, the addition of PA6 helped the composites effectively utilize the toughness of POE-g-MAH. Thus, we developed an easy method to recycle rCOC and prepare the responding composites with high strength and toughness. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8SDS of cas: 6683-19-8).

Rat Metabolism Study Suggests 3-(3,5-Di-tert-butyl-4-hydroxyphenyl)propionic Acid as a Potential Urinary Biomarker of Human Exposure to Representative 3-(3,5-Di-tert-butyl-4-hydroxyphenyl)propionate Antioxidants was written by Liu, Runzeng;Mabury, Scott A.. And the article was included in Environmental Science & Technology in 2021.Name: 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) This article mentions the following:

3-(3,5-Di-tert-butyl-4-hydroxyphenyl)propionate antioxidants, a family of synthetic phenolic antioxidants (SPAs) widely used in polymers, have recently been identified in indoor and outdoor environments. However, limited information is available concerning human exposure to these novel contaminants. In the present study, seven 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate antioxidants were analyzed in human urine samples of donors from the United States. None of the target SPAs were initially detected in the urine samples either before or after hydrolysis by β-glucuronidase, prompting us to probe the major metabolites of these SPAs. We conducted rat metabolism studies with two representative congeners, tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate) (AO1010) and N,N’-bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine (AO1024). Neither AO1010 nor AO1024 was detected in rat urine, while 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid (fenozan acid) was identified as a urinary biomarker for these 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate antioxidants. Surprisingly, fenozan acid was detected in 88% of the human urine samples before hydrolysis (geometric mean: 0.69 ng/mL) and 98% of the samples after hydrolysis (geometric mean: 10.2 ng/mL), indicating prevalent human exposure to 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate antioxidants. To our knowledge, this is the first study reporting the occurrence of fenozan acid in urine, where it can act as a potential biomarker of human exposure to 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate antioxidants. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Name: 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).

Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

A Physical-chemical Synergetic Inhibitor for Coal Spontaneous Combustion and Its Fire Prevention Performance was written by Cai, Jiawen;Yang, Shengqiang;Zhong, Yan;Song, Wanxin;Zheng, Wancheng. And the article was included in Combustion Science and Technology in 2022.Product Details of 6683-19-8 This article mentions the following:

A single phys. or chem. inhibitor can hardly meet the uttermost requirements for coal spontaneous combustion prevention. Therefore, it has become essential to develop an efficient inhibitor with multiple inhibitory properties. In light of studies on the properties of the super absorbent polymer (SAP), the main antioxidant pentaerythritol tetrakys 3-(3,5-ditert-butyl-4-hydroxyphenyl) propionate and auxiliary antioxidant tris (2,4-di-tert-butyl-pheny) phosphite, a synergistic antioxidant with both phys. and chem. inhibitory properties was prepared According to the determination of volatile matter and calorific value of coal, the optimum molar ratio of the compound antioxidant (main antioxidant: auxiliary antioxidant = 2:1) was selected. Furthermore, the optimum formulation ratio (SAP: antioxidant = 1:3) and the optimum mass ratio (12%) were determined, taking the low-temperature oxygen consumption and cross-point temperature (CPT) of coal as indexes. Three grades of metamorphic coal were selected to obtain the gaseous product, oxygen consumption at 70°C, CPTs and inhibition rate. The addition inhibitor reduced the release of CO and C₂H₄ gas and oxygen consumption, while it raised CPTs and inhibition rate of coal oxidation The inhibiting capacity of MgCl₂ is mainly at low-temperature stage, while the synergistic inhibitor has excellent congenerous phys. and chem. effect in the whole coal oxidation process. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Product Details of 6683-19-8).

Influence of acrylonitrile butadiene elastomer as polymeric co-agent for crosslinking poly(vinyl chloride) by gamma radiation was written by Gupta, Neeraj K.;Gupta, Shivani;Tedesse, Aschalew. And the article was included in Journal of Polymer Research in 2022.Name: 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) This article mentions the following:

Plasticized filled poly(vinyl chloride) (PVC) blends incorporating acrylonitrile-butadiene rubber (NBR) as an elastomeric crosslinking co-agent were subjected to gamma radiation by a Co₆₀ source for total doses 25 to 100 kGy. Changes in total insoluble contents, physicomech. properties (before and after thermal aging), morphol., spectroscopy, and dynamic mech. behavior as a function of NBR loading and total dose were investigated. An increase in total insoluble contents with both NBR loading and total dose indicates that within the parameters of the study, the blends underwent crosslinking as the predominant effect with an increase of hardness. Unaged mech. properties (tensile strength, Young’s modulus, and elongation at break) of the blends were significantly modified. These same properties, after aging at 90°C, 168 h are again modified due to further crosslinking reactions above the glass transition temperatures The obtained results indicate that there exists a loading range for NBR for which an optimal combination of room temperature and aged mech. properties may be obtained. Abrasion resistance of the blends improves due to the formation of chem. bonded networks. The mechanism of the crosslinking reaction was elucidated by Fourier transform IR spectroscopy. Electron scanning microscopy shows single-phase blend morphologies for all blends and reveals a reduction in matrix ductility on crosslinking. Dynamic mech. anal. conducted to study the change in loss tangent, storage modulus, and loss modulus at 100 kGy total dose shows an increase in these parameters and that the modification of physicomech. properties are due to both crosslinking as well as enhanced interaction between PVC and NBR. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Name: 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).

Insights into Mechanical, Thermal, and Electrical Properties of Peroxide-Cured Chlorinated Polyethylene/Ethylene Methacrylate Copolymer Blend Vulcanizates was written by Bhagabati, Purabi;Murugesan, Selvakumar. And the article was included in ACS Omega in 2021.Synthetic Route of C73H108O12 This article mentions the following:

This work unveils the effect of chem. modification of compatible elastomer blends based on the chlorinated polyethylene (CPE) and ethylene methacrylate copolymer (EMA) (60:40 ratio) using dicumyl peroxide (DCP). CPE/EMA blend vulcanizates were prepared by varying the DCP concentration from 0.5 to 3.0 wt %. All blend vulcanizates showed significant enhancement in physiomech. properties and thermal stability upon increasing the DCP concentration DCP incorporation also enhanced the compatibility between CPE and EMA rubbers, which was revealed from FTIR data and other tech. properties. Specifically, the vulcanizates with 1.5 wt % DCP showed an enormous improvement in mech. properties and glass transition temperature (T_g) due to various reasons such as cure characteristics, crosslinking densities, co-crosslinking systems, and morphol. features. Uniform distribution of DCP in both the elastomeric phases across their interphases caused co-crosslinking, which increased interphase adhesion in the blend vulcanizates. High interphase adhesion of the blend vulcanizates of 1.5 wt % DCP was directly reflected in its improved mech., thermal, flame retardation properties and enhanced oil resistance and volume resistivity in comparison to pristine CPE/EMA blend vulcanizates. Also, the volume resistivity and oil resistance properties of blend vulcanizates were found to be marginally improved upon increasing the concentration of DCP. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Synthetic Route of C73H108O12).

Processability and physico-mechanical properties of ultrahigh-molecular-weight polyethylene using low-molecular-weight olefin wax was written by Bakshi, Ashok Kumar;Ghosh, Anup K.. And the article was included in Polymer Engineering & Science in 2022.Category: esters-buliding-blocks This article mentions the following:

The influence of mol. weight of olefin wax as a plasticizer on the processability and properties of ultrahigh-mol.-weight polyethylene (UHMWPE) was thoroughly investigated in this study. Two different grades of olefin wax (H5 and 210P) were used sep. to plasticize UHMWPE. Comparative results were analyzed based on mixing torque, mech., thermal, thermo-mech., and morphol. aspects. The Gaussian math. model was applied to the internal thermo-shear batch mixing torque data to predict processability and plasticization of the resulting compounds The relatively low-mol.-weight wax (H5) seemed to be more efficient at uncoiling the entanglements among the amorphous phase of UHMWPE. The lowest degree of crystallinity range (34%-40%) and the highest nucleation rate (0.9 min^-1) were found with 10 phr H5 wax plasticized UHMWPE. The tensile strength of 30.5 MPa and elastic modulus of 127 MPa, achieved by the addition of H5 wax at 10 phr loading, confirmed the optimum effect of plasticization. The plasticization effect was also established from the loss moduli and Cole-Cole plots. A smaller number of multiple stress-induced overshoots and the inclining approach toward the viscous dominant regime with temperature sweep were observed in the case of 10 phr H5 wax composition SEM anal. revealed disappearance of interfacial crazing and interparticle boundaries progressively with the increase in H5 wax content. Overall, plasticized UHMWPE with 10 phr content of H5 wax showed the optimum processability and properties. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Category: esters-buliding-blocks).

Surface tension and interfacial tension of polyolefins and polyolefin blends was written by Charfeddine, Ilhem;Majeste, Jean-Charles;Carrot, Christian;Lhost, Olivier. And the article was included in Journal of Applied Polymer Science in 2022.Formula: C73H108O12 This article mentions the following:

This paper focuses on the calculation of the interfacial tension of two systems: low-d. polyethylene with isotactic polypropylene and high-d. polyethylene with syndiotactic polypropylene. For this, three methods to measure the interfacial tension are compared: the use of Palierne’s model, and Gramespacher and Meissner’s model, both based on addnl. elasticity or long relaxation times brought by shape recovery of dispersed phase, and ab-initio calculation, which requires the knowledge of the surface tension of the neat polymer measured at the same temperature For that, a database collected from the literature is built in the first section of this paper, whether for the studied systems or for other systems of various olefinic homopolymers or copolymers with polypropylene. The results show the effectiveness of the Gramespacher and Meissner’s model to calculate the interfacial tension of the studied systems for which the results were in agreement with ab-initio calculation and Palierne’s model. Extension of the ab-initio calculation to olefinic copolymers was proposed.
