Abstract

The invention relates to thermoplastic particulate graft polymers of a rubber (AB), consisting of a core (A) of rubber-like polymer of olefinically unsaturated monomers having softening temperatures (glass temperatures) below 0.degree. C. and a shell (B) of organopolysiloxane, and a polymer (C) of at least one ethylenically unsaturated monomer grafted into the rubber (AB) and to their use, optionally in admixture with brittle thermoplastic vinyl resins, as thermoplastic molding compositions.
