Abstract: Bead-form expandable moulding compositions of high heat resistance contain from 80 to 99 % by weight of a styrene polymer, from 1 to 20 % by weight of poly(2,6-dimethyl)-1,4-diphenyl ether, from 3 to 10 % by weight of a C3-C6-hydrocarbon as blowing agent and optionally conventional additives. They are obtained by suspension polymerisation of a solution of the polyphenylene ether in styrene.
