摘要: Expandable styrene polymers which contain a C.sub.3 -C.sub.6 -hydrocarbon as a blowing agent, an organic bromine compound as a flameproofing agent and small amounts of ammonium salt and of an organic amine give, on expansion, foams which have a particularly homogenous foam structure and a good heat insulation effect.
