摘要：

The thermal degradation of copolymers of styrene, ethylstyrene and divinylbenzene with acrylonitrile and other acrylic monomers has been studied by pyrolysis-gas chromatography at 420, 570 and 790°. The thermal degradation products were identified and determined at 570°. The thermal degradation of some chloromethylated copolymers with the same composition was also followed. It has been ascertained that the chloromethylated copolymers show characteristic behaviour in thermal degradation. This is explained by modification of the degradation mechanism of the chloromethylated copolymers with respect to the development of crosslinking processes. © 1979.
