Abstract: An expandable rubber modified styrene polymer (I) comprises (A) a continuous phase of polystyrene or a styrene comonomer containing up to 50 wt.% comonomer (B) 5-30 wt.% (w.r.t. polymer mixture) of dispersed rubber particles and (C) 2-15 pts.wt. (w.r.t. 100 pts wt. polymer mixture) of a low binding blowing agent. The rubber particles consists of a butadiene/styrene block copolymer having a compact lamella structure without polystyrene inclusions. Also claimed are: (i) a process for the production of (I) by dissolving (B) in (A) followed by polymerisation of the monomers and processing to a granular form whereby (C) is added during or after polymerisation. (ii) pre-foamed beads having pore walls made of (I).
