Abstract

Self-extinguishing, fine particulate, expandable styrene polymers for the manufacture of molded articles, containing bromine compounds and one synergist. The synergist, referred to the styrene polymer, is at least one hydrocarbon present in amounts from about 0.1 to 3% by weight and forms stable radicals at temperatures above 300 DEG C.
