Patent ID: 6951903

Claim:
A thermoplastic molding composition comprising A) at least one graft rubber that is the product of free-radical emulsion polymerization of at least one vinyl monomer in the presence of at least one rubber a) present in latex form having a glass transition temperature below 0° C. using at least one peroxodisulfate compound as initiator, B) at least one graft rubber that is the product of free-radical emulsion polymerization of at least one vinyl monomer in the presence of at least one rubber b) present in latex form having a glass transition temperature below 0° C. using at least one azo compound as initiator, C) at least one graft polymer that is the product of solution, bulk or suspension polymerization of styrene and acrylonitrile grafted phase in a weight ratio of 90:10 to 50:50 therebetween, in the presence of a rubber, wherein the rubber contains in copolymerized form 0 to 50 wt. % of a vinyl monomer and wherein the weight ratio of polymerized and grafted monomers to the rubber is 50:50 to 97:3.
