    Abstract: Expandable molding compositions having high heat distortion resistance and containing from 80 to 99% by weight of a styrene polymer, 1 to 20% by weight of poly-1,4-phenylene sulfide, from 1 to 10% by weight of a C3-C6-hydrocarbon as blowing agent and, if desired, customary additives, are obtained by suspension polymerization of a solution of the polyphenylene sulfide in styrene.

    Abstract: Expandable styrene polymers which contain from 10 to 90% by weight of a crosslinked styrene-diene copolymer containing from 2 to 45% by weight of the diene, and from 1 to 10% by weight of a C3- to C6-hydrocarbon as blowing agent can be processed to give foams which have high resistance to aromatics.
