The copolymerisation of tetrahydrofurfuryl methacrylate and methyl methacrylate

open access: yesPolymer Gels and Networks, 1996
The 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.

Preparation and degradation of copolymers of methyl methacrylate with alkali metal methacrylates—I. Copolymerization parameters for the systems methyl methacrylate-lithium methacrylate, methyl methacrylate-sodium methacrylate and methyl methacrylate-potassium methacrylate

European Polymer Journal, 1978
Abstract Copolymerizations of methyl methacrylate with the Li, Na and K salts of methacrylic acid have been studied in methanol solution at 60°. Reactivity ratios have been calculated by the methods due to Mayo and Lewis, Fineman and Ross and Peckham. The rate of copolymerization decreases as the size of the metal cation increases, in contrast to the

Methods for the Synthesis of Methacrylic Acid and Methacrylates

Kataliz v promyshlennosti, 2020
The 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
