Abstract

An impact-resistant thermoplastic molding material, containing polystyrene as the matrix, and, dispersed therein, two elastomeric polymers or copolymers I and II composed entirely or predominantly of 1,3-dienes and containing particles of different mean size, namely, in I, particles from 0.2 to 0.6 .mu.m in size and having capsule particle morphology, and, in II, particles from 2 to 8 .mu.m in size, having cell particle or coil particle morphology.
