PROCESS FOR PRODUCING STABILIZED POLYSTYRENE COMPOSITIONS

摘要

PROCESS FOR PRODUCING STABILIZED POLYSTYRENE COMPOSITIONS A process is provided for the production of polystyrene and poly(p-methylstyrene) containing polymer stabilized, said polymer stabilizer being present during all or part of the polymerization process. The polymer stabilizer is a mixture of a hindered phenol compound and a polyphosphite compound. There is also provided a process for the production of foam polymer using the polystryrene or poly(p-methylstryrene) containing polymer stabilizer.
