A thermoplastic molding composition having an improved profile of properties is disclosed. The composition contains A) a graft rubber that is a product of free-radical emulsion polymerization of vinyl monomers in the presence of rubber a) that is present in latex form and having a glass transition temperature below 0° C., using at least one peroxydisulfate compound as an initiator, and B) a graft rubber that is a product of free-radical emulsion polymerization of vinyl monomers in the presence of at least one rubber b) that is present in latex form and having a glass transition temperature below 0° C., using at least one redox system as an initiator, and C) at least one graft polymer, that is a product of solution, bulk or suspension polymerization of a grafted phase that contains a member selected from the group consisting of styrene and acrylonitrile in a weight ratio of 90:10 to 50:50 therebetween, in the presence of a rubber, and wherein the weight ratio of introduced graft monomers to introduced rubber is 50:50 to 97:3. |
