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.

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.

Abstract: Bead-form expandable styrene polymers are obtained by suspension polymerization of styrene with addition of from 1 to 10% by weight of C3- to C6-hydrocarbons as blowing agents and, if desired, customary additives, where (a) the polymerization is initiated by rapidly heating the polymerization batch to form 80 DEG to 90 DEG C. within a maximum of 2 hours, (b) subsequently allowing the reaction temperature to increase to from 120 DEG C. to 130 DEG C. by from 8 DEG to 17 DEG C. per hour, and (c) the conversion is formed 30 to 60% when 100 DEG C. is reached, and (d) the conversion is 80% or more when the maximum temperature is reached, and (e) the batch is subsequently kept at from 100 DEG to 130 DEG C. until the residual monomer content in the polymer has dropped to less than 0.1%.
