摘要: Particulate self-extinguishing thermoplastic molding compositions based on styrene polymers containing volatile blowing agents are surface-coated with an organic bromine compound and, to stabilize the bromine compound against photodegradation, a N-hydroxyphenylbenzotriazole or a hydroxybenzophenone. The molding compositions may be used for the manufacture of foams by expanding the blowing agents at elevated temperatures.
