摘要

α-methylstyrene-methyl methacrylate emulsion copolymerizations have been investigated at various temperatures (60, 70, 85°C) on the whole composition range. The kinetic behavior has been studied, such as conversion, particle size, and the average number of radicals per particle (n over-bar ), as well as the following characteristics of the copolymers: composition, microstructure, molecular weights (MWD), and glass transition temperature (Tg). One of the main results is the possibility to synthesize stable copolymers with high Tg (i.e., 132-140°C).
