Abstract

Thermoplastic molding compositions based on thermoplastic polyesters (a.sub.1), graft polymers incorporating acrylate rubbers as grafting bases (a.sub.2), copolymers of aromatic vinyl monomers and acrylonitrile or methacrylonitrile (a.sub.3) which contain a polymeric component (B) having carboxyl, carboxyl derivative, hydroxyl or epoxy groups or, alternatively, where graft polymers (a.sub.2) or copolymers (a.sub.3) carry such groups have a balanced range of properties.
