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.
