    Abstract: Materials composed of styrene polymers, hydrocarbons or fluorine-containing halogen hydrocarbons as blowing agents and a cell regulator and other additives, contain 0.1 - 8 wt.% polyisobutylene of M.W. 1000 - 100000 and 0.5 - 5 wt.% of an ester of phthalic acid or of an aliphatic acid with 10- 40 C atoms. Pref. shaped articles of foam polystyrene are prepared by extruding the above material. Advantages lie in the increased resistance to cold, improved ductility and the finer, more homogeneous cell-structure.
