摘要：
Foam sheets of high compressive strength are produced by extruding a mixture of a styrene polymer and from 5 to 16% by weight of a blowing agent mixture containinga) from 3 to 70% by weight of an alcohol or ketone having a boiling point of from 56.degree. to 100.degree. C.,b) from 5 to 50% by weight of carbon dioxide andc) from 0 to 90% by weight of a saturated C.sub.3 - to C.sub.5 -hydrocarbon and/or of a hydrogen-containing chlorofluorocarbon or fluorinated hydrocarbon boiling at from -30.degree. to +30.degree. C.
