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 C.sub.3 -to C.sub.6 -hydrocarbon as blowing agent can be processed to give foams which have high resistance to aromatics.
