Abstract:

Polyvinylbenzene and copolymers of styrene with divinylbenzene and with trivinylbenzene were pyrolyzed in a vacuum in the temperature range 240 degrees to 450 degrees C. The results indicate a gradual increase in thermal stability of the copolymers as the amount of crosslinking agents divinylbenzene and trivinylbenzene is increased. Thermal degradation studies of polystyrene, polymethylene, polytetrafluoroethylene, poly-alpha-methylstyrene, polypropylene, polyisobutylene and PMMA showed that the higher the temperature and pressure of pyrolysis the greater is the fragmentation of the degradation products. Instrumentation for the study of the thermal degradation of organic polymers was also investigated.
