Abstract: A heat-sealable multilayer film comprising: a) 1% to 50% by weight of heat-sealable polymer layer (A), b) 1% to 99% by weight of polymer layer (C), and c) 0% to 95% by weight of polymer layer (B), with polymer layer (A) comprising: A1) 20% to 90% by weight of impact-resistant polystyrene and A2) 5% to 50% by weight of vinylaromatic-diene block copolymer; and polymer layer (B) comprising impact-resistant polystyrene, vinylaromatic-diene block copolymer, and/or mixtures of styrene homopolymers or vinylaromatic-diene graft copolymers with vinylaromatic-diene block copolymers; and polymer layer (C) having a melting temperature of ≥170° C.; and polymer layer (A) comprising) i) 66% to 99% by volume of a vinylaromatic hard phase and ii) 1% to 34% by volume of a diene soft phase surrounded by the hard phase and taking the form of spheres/cylinders.

Abstract: The invention relates to expandable polymer particles based on styrene polymers, to a process for the preparation thereof and to the use of the expandable polymer particles in a molded foam part. The polymer particles contain A) 87 to 99 wt. % of one or more styrene polymers (A), in relation to the total weight of (A), (B) and (C); B) 1 to 10 wt. % of one or more foaming agents (B); C) 0 to 3 wt. % of one or more nucleators or nucleating agents C); and optionally further additives (Z) in amounts which do not impair the domain formation and the foam structure resulting therefrom.
