In this work, new bio-based copoly(ester amide)s were synthesized by a two-step melt polycondensation process using 2,5-furanedicarboxylic acid di-Me ester (DMFDC), 1,3-propanediol (PDO), and 1,3-diaminopropane (DAP) with different DAP content. The chem. structure of the obtained poly(trimethylene 2,5-furandicarboxylate)-co-poly(propylene furanamide) (PTF-co-PPAF) copolymers was confirmed by NMR (¹H NMR) and Fourier-transform IR (FTIR) spectroscopy. Gas chromatog./mass spectrometry was used to provide more details of the polycondensation process. Thermal properties of the obtained materials were characterized by means of differential scanning calorimetry (DSC), thermogravimetric anal. (TGA), and dynamic-mech. thermal anal. (DMTA). The copolymers were amorphous and their glass transition temperature increased with the increase in the poly(propylene furanamide) (PPAF) content. The synthesized PTF-co-PPAF copolymers exhibited improved thermal and thermo-oxidative stability up to 300°C. In addition, from the performed mech. tests, it was found that along with the increase in PPAF content, Young’s modulus increased, while at the same time, the value of elongation at break decreased. 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).

The use of bioplastic mulch in agriculture has increased dramatically in the last years throughout the world. Nowadays, biodegradable materials for mulching films strive to constitute a reliable and more sustainable alternative to classical materials such as polyethylene (PE). The main challenge is to improve their durability in the soil to meet the required service length for crop farming by using benign and sustainable antioxidant systems. Here, we report the design and fabrication of biodegradable materials based on polybutylene (succinate adipate) (PBSA) for mulching applications, incorporating a fully biobased polymeric antioxidant deriving from ferulic acid, which can be extracted from an industrial byproduct. Poly-dihydro (ethylene ferulate) (PHEF) from ferulic acid was synthesized by a two-step polymerization process. It is characterized by improved thermal stability in comparison with ferulic acid monomer and therefore suitable for common industrial processing conditions. Different blends of PBSA and PHEF obtained by melt mixing or by reactive extrusion were prepared and analyzed to understand the effect of the presence of PHEF. The results demonstrate that PHEF, when processed by reactive extrusion, presents a remarkable antioxidant effect, even in comparison with com. additives, preserving a high level of the mech. properties of the PBSA matrix without affecting the biodegradable character of the blend. 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).

Viscoelasticity, Tensile Properties, and Microstructure Development in Cyclic Olefin Copolymer/Polyolefin Elastomer Blends was written by Pei, Xiaoshan;Li, Yanxiao;Zhao, Shicheng;He, Xuelian. And the article was included in Macromolecular Chemistry and Physics in 2022.COA of Formula: C73H108O12 This article mentions the following:

The new ethylene/cyclic olefin copolymers (COCs) are a major breakthrough in traditional polyolefins made available by metallocenes, but its high brittleness restricts the applications. Ethylene/1-octene copolymer (POE) with similar backbones is blended with COCs to compensate the rigidity of cyclic segments. Field emission scanning electron microscope photos and Raman spectra demonstrate the existence of abundant phase interfaces between POE and COC, and the phase structure changes from spherical droplets, of partial continuity to cocontinuity with rising POE components. The phase changes are considered as corresponding to the formation, expansion, and coalescence of droplets at melting state according to Van Gurp curves, Han plot, and Cole-Cole plot. Viscoelastic data show that the storage modulus, loss modulus, and complex viscosity reach a high value at medium POE contents. Furthermore, the tensile strength and fracture energy increases and then decreases, the elongation at break increases and Young’s modulus reduces with the increment of POE percentage. Because of the large spherical and ellipsoidal structures and abundant interfaces, the synchronous reinforcement and toughness come true at a medium ratio of POEs. Dynamic mech. anal. confirms the existence of the interfacial layer, and the interfacial layer becomes more pronounced with the rising POE contents exactly as the morphol. and rheol. findings. 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: 6683-19-8COA of Formula: C73H108O12).

Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.COA of Formula: C73H108O12

High orientation structure in UHMWPE / BN composites continuously obtained by elongational flow field leading to superior thermal conductivity was written by He, Guangjian;Lin, Zhihao;Yin, Xiaochun;Feng, Yanhong. And the article was included in Journal of Applied Polymer Science in 2022.Formula: C73H108O12 This article mentions the following:

Ultra-high-mol.-weight polyethylene/boron nitride (BN) composites have been continuously prepared successfully by eccentric rotor extruder (ERE) based on elongational flow. Optical microscopy (OM), SEM (SEM), x-ray diffraction (XRD), thermal conductivity test, heat-dissipation test, and tensile test were performed to investigate the orientation structure, thermal conductivity, mech. properties, and insulation properties. The orientation factor and thermal conductivity of the composites prepared by ERE were 79.3 and 3.75 W·m^-1·K^-1, which were much higher than those of composites prepared with a torque mixer (14.7 and 2.73 W·m^-1·K^-1, resp.). OM and SEM showed that the BN sheets were in contact inside the composites and formed an efficient thermal conductivity network. Besides, the composites prepared by ERE had satisfactory mech. and insulation properties (>10¹³ Ω·cm). This study provides exptl. and theor. guidance for industrial preparation of polymer/layered-filler functional composites. 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: 6683-19-8Formula: C73H108O12).

Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Formula: C73H108O12

Fabrication of highly efficient phenylphosphorylated chitosan bio-based flame retardants for flammable PLA biomaterial was written by Ma, Xiaobing;Wu, Ningjing;Liu, Pengbo;Cui, Hongli. And the article was included in Carbohydrate Polymers in 2022.Related Products of 6683-19-8 This article mentions the following:

Modified chitosan (CS)-based flame retardants exhibit promising prospects owing to their sustainability, biodegradability, and good charring properties. A series of novel modified-CS bio-based flame retardants (phenylphosphorylated CS (PhPCS) and phenylphosphoramidated CS (PhPNCS)) were prepared by the phosphorylation and phosphoramidation reactions of CS with phenylphosphoryl dichloride and tetraethylenepentamine, resp. Bio-based PhPCS and PhPNCS exhibited excellent flame retardancy efficiency for poly(lactic acid) (PLA). The limited oxygen index (LOI) values of the PLA/3 wt% PhPCS and PLA/3 wt% PhPNCS biocomposites increased to 29% and 27%, resp., and they both achieved a V-0 rating during the UL-94 vertical combustion test. However, the mech. properties of the PLA/PhPCS biocomposites decreased with increasing PhPCS content. The mech. strengths of the PLA/PhPNCS biocomposites were better than those of the PLA/PhPCS biocomposites owing to the reactive compatibilization of the interface between the amino and carboxyl end groups of the PhPNCS nanoparticles and PLA matrix, resp. 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: 6683-19-8Related Products of 6683-19-8).

In order to develop a new wood product suitable for outdoor applications, a high m.p. polyethylene wax was used for high-pressure impregnation treatment of wood. Properties of impregnated wood were studied. Wax in molten state was stable with low viscosity, good fluidity, and easily penetrate into the wood under high pressure. Full-cell process included vacuum (-0.06 MPa for 30 min), high-pressure impregnation (0.75 MPa for 3 h) and pressure release (30 min). Wax contents of treated lodgepole pine (Pinus contorta Douglas ex Loudon.) and eucalyptus (Eucalyptus saligna) were 0.205 g/cm³ and 0.321 g/cm³, resp. Cell gaps and cell cavities of wood were filled with polyethylene wax. Nanoindentation tests showed that longitudinal mech. properties of wood cell walls were weakened after impregnation. After a 3 h high-pressure impregnation, hardness of lodgepole pine wood cell walls was reduced by 35.1%, and the modulus of elasticity was reduced by 4.9%. Treated wood had a much lower water absorption and swelling rate than untreated wood, its weathering resistance as well as insect resistance were better. 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: 6683-19-8Recommanded Product: 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)).

Toughening and reinforcing waste polypropylene with POE / nano-SiO₂ under elongational flow was written by He, Hezhi;Gao, Jun;Wang, Yi;Zhu, Zhiwen;Liu, Yufan;Tian, Guidong;Xu, Li;Huang, Zhaoxia. And the article was included in Journal of Applied Polymer Science in 2022.COA of Formula: C73H108O12 This article mentions the following:

Due to the white pollution, the recycling of waste plastics has attracted more and more attention. In this research, waste polypropylene/Ethylene-octene elastomer/nano-SiO₂ composites (wPP/POE/SiO₂) were melt-blended using an Eccentric Rotor Extruder (ERE) dominated by elongational flow field and a Torque Rheometer (TR) dominated by shear flow field, resp. The micromorphol., mech., crystallization, thermal and rheol. properties of wPP/POE/SiO₂ blends were studied. Compared to the blends fabricated by TR, the wPP/POE/SiO₂ blends with different compositions fabricated by ERE showed higher tensile strength, flexural strength, and modulus. Particularly, without sacrificing the tensile strength, the notched impact strength of the wPP/POE/SiO₂ blends fabricated by ERE increased to 13.53 kJ/m², a factor of 3 times larger than that of neat wPP. The enhancement of impact strength of the wPP/POE/SiO₂ blends fabricated by ERE could be ascribed to the good dispersion of POE under elongational flow and the increase of PP crystallinity. The finding from this work provides an efficient way to recycle wPP. 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: 6683-19-8COA of Formula: C73H108O12).

The chances of thermooxidation stabilization of poly(3-hydroxybutyrate) during processing-A critical evaluation was written by Tochacek, Jiri;Prikryl, Radek;Mencik, Premysl;Melcova, Veronika;Figalla, Silvestr. And the article was included in Journal of Applied Polymer Science in 2021.Product Details of 6683-19-8 This article mentions the following:

The performance of a series of thermooxidn. stabilizers was investigated in poly(3-hydroxybutyrate) (PHB) during processing by multiple extrusion at 190鎺矯. The issue was to find out if PHB may be processing stabilized or not. Phenols of different steric hindrance, phosphites, amine oxide, hydroxylamine, lactone, hindered amine and carbodiimide were tested as potential stabilizers and their efficiencies compared with non-stabilized polymer as a reference Multiple extrusion data was evaluated using the processing degradation index (PDI) formerly designed for polypropylene. Changes in mol. weight were monitored as well. The results have shown that none of the stabilizing structures, currently successfully used in other polymers, have the ability to protect PHB. This indirectly implies that no radical chain scission takes place during PHB processing, i.e. no thermooxidn. takes place. Moreover, nearly all of the tested structures act as prodegradants in PHB, some of them very strong. The strongest ones contain P or N atoms with asym. free electron pairs in their mols. that evidently accelerate the main degradation mechanism of PHB-thermally induced cis-elimination. 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).

Amine-functionalized micron-porous polymer foams with high CO₂ adsorption efficiency and exceptional stability in PSA process was written by Yang, Chuanruo;Xiong, Yuxin;Chen, Jian;Jin, Junsu;Mi, Jianguo. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2021.Recommanded Product: 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:

The advantages and disadvantages of amine-based materials for adsorptive CO₂ capture have been well addressed so far. In order to maintain their high adsorption efficiency and long-term stability in treatment of complex flue gas, here we selected linear pentaethylenehexamine (PEHA) with in-depth epoxide functionalization to inhibit O₂, CO₂, and SO₂ induced deactivation. We enveloped the functionalized PEHA into the hydrophobic polypropylene/polyolefin elastomer open-cell foams via epoxy resin crosslinking to prevent amine leaching and reduce water adsorption. Using the phase inversion and the supercritical CO₂ foaming technologies, we controlled the cells with micron sizes and 88% porosity. The loss of adsorption capacity due to amine conversion has been successfully compensated by improving the loading ratio up to 65 weight%. To the best of our knowledge, this is the highest loading among amine-functionalized materials. Coupled with the PSA process, the stability of PEHA has been extended to the maximum extent in the prerequisite of ensuring high CO₂ adsorption efficiency. 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: 6683-19-8Recommanded Product: 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)).

Properties and structure of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) filaments for fused deposition modelling was written by Kovalcik, Adriana;Smilek, Jiri;Machovsky, Michal;Kalina, Michal;Enev, Vojtech;Dugova, Hana;Cernekova, Nicole;Kovacova, Maria;Spitalsky, Zdenko. And the article was included in International Journal of Biological Macromolecules in 2021.Category: esters-buliding-blocks This article mentions the following:

Fused deposition modeling (FDM) is a process of additive manufacturing allowing creating of highly precise complex three-dimensional objects for a large range of applications. The principle of FDM is an extrusion of the molten filament and gradual deposition of layers and their solidification. Potential applications in pharmaceutical and medical fields require the development of biodegradable and biocompatible thermoplastics for the processing of filaments. In this work, the potential of production of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P(3HB-co-4HB)) filaments for FDM was investigated in respect to its thermal stability. Copolymer P(3HB-co-4HB) was biosynthesised by Cupriavidus malaysiensis. Rheol. and mech. properties of the copolymer were modified by the addition of plasticizers or blending with poly(lactic acid). Thermal stability of mixtures was studied employing thermogravimetric anal. and rheol. analyses by monitoring the time-dependent changes in the complex viscosity of melt samples. The plasticization of P(3HB-co-4HB) slightly hindered its thermal degradation but the best stabilization effect was found in case of the copolymer blended with poly(lactic acid). Overall, rheol., thermal and mech. properties demonstrated that the plasticized P(3HB-co-4HB) is a potential candidate of biodegradable polymer for FDM processes. 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).
