Hamulic, Damir published the artcileThe influence of length of alkyl chain on the chemical structure and corrosion resistance of silica-polyacrylic hybrid coatings on structural steel, Product Details of C16H30O2, the main research area is methacrylic polysiloxane anticorrosive coating transparency morphol wettability impedance.

Hybrid coatings were prepared, via a sol-gel route from 3-(trimethoxysilyl)propyl methacrylate (MAPTMS), tetra-Et orthosilicate (TEOS), and derivatives of methacrylate (methyl-, ethyl-, butyl-, hexyl-, octyl- and dodecyl methacrylate). The main goal of this study was to evaluate how the length of the alkyl chain of the ester part of a methacrylate influences the anti-corrosion property of the coatings. Fourier transform IR spectroscopy, NMR spectroscopy, contact angle measurements, and SEM with chem. anal. were used to determine the chem. composition, structure, wettability and morphol. of the coatings. The contact angle of the coatings increased from methyl- to butyl-containing coating (from 60° up to 80°); at the same time the surface free energy decreased. For longer chains, a plateau was reached (≈75°), which was in contrast to the prediction that a longer chain would result in reduced wettability due to its nonpolar alkyl part. The anti-corrosion behavior in 3.5 weight % NaCl of the coatings deposited on structural steel was studied by electrochem. impedance spectroscopy. The coatings with Et and Bu groups exhibited the best anti-corrosion performance and remained intact over six months of immersion. The related values of impedance magnitude at low frequency was 1010 Ω cm2 after six months. This high corrosion resistance was due to the appropriate combination of condensation degree and wettability. Coatings with longer alkyl chains (hexyl, octyl, and dodecyl) showed poor corrosion resistance due to lower heterocondensation and a larger nonpolar effect that resulted in non-homogenous mixing, which could not produce dense and protective coatings.

Khidr, T. T. published the artcilePreparation and evaluation of n-alkyl methylacrylatemethylacrylate-vinyl acetate-methacrylic acid terpolymers as pour point depressant for fuel, Name: Dodecyl 2-methylacrylate, the main research area is alkyl methylacrylate vinyl acetate terpolymer pour point depressant fuel.

A variety of techniques have been employed in order to reduce problems caused by the crystallization of paraffin during the production Four different alkyl chain length of n-alkyl methacrylate-vinyl acetate-methacrylic acid terpolymers were prepared and characterized by the IR spectrometer, and the mol. weight of the prepared additives was determined by using gel permeation chromatog. anal. The performance of the prepared terpolymers as pour point depressants additives for fuel oil. The efficiency of the prepared compounds on pour point depressants for fuel oil increases by increasing the concentration of these additives and the alkyl chain length of n-alkyl methacrylate. The X- ray diffractometer patterns of wax in the absence and presence of investigated additives were studied. Comparison of morphologies and structures of waxy crystals in fuel oil beneficiated with and without a pour point depressant was made by micro photog. studies which show the modification in wax morphol. due to the additive.

Iborra, Agustin published the artcileSynthesis of lauryl methacrylate and poly(ethylene glycol) methyl ether methacrylate copolymers with tunable microstructure and emulsifying properties, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is lauryl methacrylate polyethylene glycol methyl ether copolymer.

In this work we study the synthesis and properties of copolymers constituted of lauryl methacrylate and poly(ethylene glycol) Me ether methacrylate monomers, prepared by atom transfer radical copolymerization in the entire composition range (with low and high monomer conversion). We propose a description of the copolymer microstructure, and evaluate the composition drift effect in the thermal and solution properties of the obtained copolymers. NMR was used to determine the chem. composition of the copolymers, while differential scanning calorimetry and themogravimetric anal. was employed to understand the thermal chracteristics. Rheol. studies were conducted to obtain the viscosity and viscoelastic properties that were correlated with thermal transitions at different temperatures Finally, dynamic light scattering (DLS) and surface tension measurements were used to evaluate the copolymer solution properties. The incorporation of an oil phase in the self-assembled aggregates was evaluated by DLS and characterized by at. force microscopy, diffusion-ordered spectroscopy NMR and nuclear Overhauser effect NMR spectroscopy. Our results suggest a longer sequence of LMA units in the copolymer chain and a drift effect in the case of high monomer conversions. A clear dependence on copolymer composition and microstructure to disperse an oil phase in water was observed We believe that these results bring valuable knowledge that advances the field of macrosurfactants as well as their potential applications in oil recovery and other industrial processes.

Su, Esra published the artcileSolvent-Free UV Polymerization of n-Octadecyl Acrylate in Butyl Rubber: A Simple Way to Produce Tough and Smart Polymeric Materials at Ambient Temperature, Application of Dodecyl 2-methylacrylate, the main research area is solver free photopolymerization octadecyl acrylate butyl rubber smart material; butyl rubber; interconnected IPNs; n-octadecyl acrylate; self-healing; shape memory.

One of the most fascinating challenges in recent years has been to produce mech. robust and tough polymers with smart functions such as self-healing and shape-memory behavior. Here, we report a simple and versatile strategy for the preparation of a highly tough and highly stretchable interconnected interpenetrating polymer network (c-IPN) based on butyl rubber (IIR) and poly(n-octadecyl acrylate) (PC18A) with thermally induced healing and shape-memory functions. Solvent-free UV polymerization of n-octadecyl acrylate (C18A) at 30 ± 2°C in the presence of IIR leads to IIR/PC18A c-IPNs with sea-island or co-continuous morphologies depending on their IIR contents. The lamellar crystals with a melting temperature Tm of 51-52°C formed by side-by-side packed octadecyl (C18) side chains are responsible for more than 99% of effective cross-links in c-IPNs, the rest being hydrophobic associations and chem. cross-links. The c-IPNs exhibit varying stiffness (9-34 MPa), stretchability (72-740%), and a significantly higher toughness (1.9-12 MJ·m-3) than their components, which can be tuned by changing the IIR/PC18A weight ratio. The properties of c-IPNs could also be tuned by incorporating a second, noncrystallizable hydrophobic monomer, namely, lauryl methacrylate (C12M), in the melt mixture We show that the lamellar clusters acting as sacrificial bonds break at the yield point by dissipation of energy, while the ductile amorphous continuous phase keeps the structure together, leading to the toughness improvement of c-IPNs. They exhibit a two-step healing process with >90% healing efficiency with respect to the modulus and a complete shape-recovery ratio induced by heating above Tm of alkyl crystals. The temperature-induced healing occurs via a quick step where C18 bridges form between the damaged surfaces followed by a slow step controlled by the interdiffusion of C18A segments in the bulk. We also show that the strategy developed here is suitable for a variety of rubbers and n-alkyl (meth)acrylates of various side-chain lengths.

Guan, Lin published the artcileHighly transparent and stretchable hydrogels with rapidly responsive photochromic performance for UV-irradiated optical display devices, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is hydrogel photochromic optical display flexible acrylic.

Photochromic hydrogels have attracted considerable attention owing to their potential application in optical devices. However, the weak mech. properties severely limited their applications. Here, a novel photochromic hydrogel with high transparency, high stretchability and rapid photochromic responsiveness has been successfully designed and prepared by introducing a redox photochromic material (Mo) into the hybrid hydrogel. The photochromic hydrogel with rapid photochromic response achieved discoloration process within only 3 s and the fading process could be easily performed under the air environment. Moreover, the ability to rewrite and erase optical information have been implemented on the photochromic hydrogels. Therefore, this strategy of photochromic hydrogel would contribute to design a new generation of optical display devices.
