Methods for the Synthesis of Methacrylic Acid and Methacrylates
Kataliz v promyshlennosti, 2020The review provides an analysis of the literature on the existing processes for obtaining an important organic product – methacrylic acid and its ester – methyl methacrylate. The main methods of their industrial production are the synthesis from acetone and hydrocyanic acid (the acetone cyanohydrin method) and catalytic syntheses from petrochemical raw

The copolymerisation of tetrahydrofurfuryl methacrylate and methyl methacrylate
Polymer Gels and Networks, 1996The bulk copolymerisations of tetrahydrofurfuryl methacrylate, THFMA, and methyl methacrylate, MMA, were carried to low conversion at 60 degrees C, using benzoyl peroxide, BPO, as the initiator. The compositions of the copolymers were determined using C-13 NMR spectroscopy.

Five binary formulations were prepared from methyl methacrylate (MMA) and methacrylic acid (MAA) monomers, and six ternary formulations were prepared from polysols of 30% wt polymethyl methacrylate (PMMA)/MMA and MAA. Using thermal analyses (DSC and TGA) the polymerization kinetics, condition of postcuring, relative amount of residual monomers, and ...

The copolymerization of phenyl methacrylate with methacrylic acid
Polymer Science U.S.S.R., 1970Copolymers of methacrylic acid with its esters are used as models in the hydrolysis s tudy of the respective polymethacrylates [1]. The knowledge of copolymerization constants rl and r2 permits the calculation of the acid and ester unit distribution in the copolymer chains. In this event the kinetic s tudy of the hydrolysis of copolymer samples enables

Enzymatic synthesis of sorbitan methacrylate: Comparison of methacrylic acid and vinyl methacrylate
Biochemical Engineering Journal, 2006Abstract “Biomaterials” is a generic term which refers to a variety of medical material which is designed to be in direct contact with living tissue. Clearly, biomaterials must be carefully and microscopically fabricated for optimal acceptance within the living organism, in both functional and structural senses. In this study, the enzymatic synthesis

Terpolymers composed of methyl methacrylate (MMA), polydimethylsiloxane methacrylate (PDMSMA), and methoxypolyethyleneglycol methacrylate (MPEGMA), having different compositions were synthesized. Platelets were not adsorbed onto terpolymer surfaces composed of 50 wt% MMA, 25 wt% PDMSMA and 25 wt% MPEGMA, while on terpolymers with the other compositions,

Copolymerization of methacrylic acid with methyl methacrylate by SET‐LRP
Journal of Polymer Science Part A: Polymer Chemistry, 2010AbstractSingle‐electron transfer living radical polymerization (SET‐LRP) has developed as a reliable, robust and straight forward method for the construction well‐defined polymers. To span an even larger variety of functional monomers, we investigated the copolymerization of methyl methacrylate with methacrylic acid by SET‐LRP.
