Catalysis for the synthesis of methacrylic acid and methyl methacrylate

Chemical Society Reviews, 2018
Methyl methacrylate (MMA) is a specialty monomer for poly methyl methacrylate (PMMA) and the increasing demand for this monomer has motivated industry to develop clean technologies based on renewable resources.

Polymerization of Methyl Methacrylate

Nature, 1946
IN a general survey of the polymerization of vinyl compounds using the method previously described1, we have studied methyl methacrylate, and have found that it presents features of some interest.

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

The transport of methyl methacrylate monomer in poly(methyl methacrylate)

Journal of Applied Polymer Science, 1975
The absorption kinetics and equlibria of methyl methacrylate monomer into poly(methyl methacrylate) were studied over a range of penetrant activities. The interval sorption kinetics at elevated activities were determined, compared, and contrasted with the integral sorption experiments in previously unpenetrated film samples.

The copolymerisation of tetrahydrofurfuryl methacrylate and methyl methacrylate

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

The initiation of polymerization of methyl methacrylate by the poly(methyl methacrylate) anion

Journal of Polymer Science, 1960
AbstractAddition of methyl methacrylate monomer to poly(methyl methacrylate) which has been polymerized with fluorenyllithium or sodium‐naphthalene in tetrahydrofuran at −78°C. produces high conversion of monomer to polymer. By a comparison of the number‐average molecular weights before and after the addition of the second monomer, it is demonstrated ...
