Abstract: Expandable styrene polymers comprising a) from 50 to 98% by weight of polystyrene and b) from 2 to 50% by weight of a styrene-soluble elastomer and possibly also containing from 1 to 15% by weight, based on the sum of a) and b), of a low-boiling blowing agent and optionally conventional additives are expanded to give foams having a density of from 0.01 to 0.1 g/cm and increased elasticity. They can be prepared by suspension polymerisation of a styrene solution of the elastomer and addition of a blowing agent.

Abstract: Expandable styrene polymers containing a) 80 to 99% by weight of polystyrene, b) 1 to 20% by weight of a styrene-soluble polymer having a softening temperature above 140 DEG C, c) 3 to 10% by weight, based on the sum of a) and b), of a C3- to C6-hydrocarbon as a blowing agent, and optionally d) conventional additives, in which the mixture of components a) and b) has a melt flow index MFI 200/5 of between 15 and 30, are distinguished by high heat distortion resistance and good expandability.

Abstract: Flame-resistant, expandable styrene polymers containing a styrene (co)polymer, from 0.4 to 6% by weight of hexabromocyclododecane having a mean particle size of from 1 to 50 mu m, the particles being provided with a firm coating which has a thickness of from 1/100 to 1/10 of the particle diameter and is insoluble in water and styrene, from 1 to 10% by weight of a C3- to C6-hydrocarbon as blowing agent, and, if desired, customary additives, are distinguished by a reduced internal water content and can be processed to form foams which have an improved foam structure and high UV stability.
