Abstract

Expandable, thermoplastic polymer bead material composed of a multiphase polymer mixture which comprises blowing agent and has at least one continuous phase of a thermoplastic polymer, where at least two different disperse phases P1 and P2 are present, disperse in the continuous phase, and also to processes for its production, and to use for the production of elastic molded foams.
