Abstract:
A composition containingA) at least one graft rubber that is a product of free-radical emulsion polymerization of at least one vinyl monomer in the presence of at least one rubber a) that is present in latex form and having a glass transition temperature below 0Â° C., using at least one peroxydisulfate compound as an initiator, B) at least one graft rubber that is a product of free-radical emulsion polymerization of at least one vinyl monomer in the presence of at least one rubber b) that is present in latex form and having a glass transition temperature below 0Â° 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 at least one 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 graft monomers to rubber is 50:50 to 97:3.
