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

A Facile Photocontrolled Iodine-Mediated Reversible-Deactivation Radical Polymerization System: Solution Polymerization of Methacrylates under Irradiation with NIR LED Light.

Angewandte Chemie, 2019
Herein, near-infrared (NIR) photocontrolled iodine-mediated reversible-deactivation radical polymerization (RDRP) of various methacrylates without external photocatalyst was developed using alkyl iodide (e.g., 2-iodo-2-methylpropionitrile, CP-I) as the ...

Isocyanato Urethane Methacrylates Derived from Hydroxyethyl Methacrylate

Journal of Dental Research, 1980
Isocyanato urethane methacrylates were synthesized from five diisocyanates and hydroxyethyl methacrylate. They may be homopolymerized or copolymerized with other methacrylates by the usual free radical methods of initiation and have potential as adhesion-promoting agents for dentin.

Thermoforming polymethyl methacrylate

The Journal of Prosthetic Dentistry, 1995
This study characterized a range of commercially available polymethyl methacrylate sheets with respect to molecular weight, residual monomer content, and glass transition temperature and then developed a thermoforming procedure that produced visually satisfactory thermoformed polymethyl methacrylate specimens.
