Abstract:
A thermoplastic molding composition comprisingA) at least one first grafted rubber that is a product of free-radical emulsion polymerisation wherein at least one vinyl monomer is polymerized in the presence of at least one rubber a) that is present in the form of a latex, said rubber having a glass transition temperature lower than 0Â° C., the polymerization being initiated by at least one compound selected from the group consisting of ammonium persulfate, potassium persulfate and sodium persulfate, B) at least one second grafted rubber that is a product of free-radical emulsion polymerisation wherein at least one vinyl monomer is polymerized in the presence of at least one rubber b) that is present in the form of a latex, said rubber having a glass transition temperature lower than 0Â° C., the polymerization being initiated by at least one azo compound, and optionally C) at least one thermoplastic, rubber-free polymer that is the product of the polymerisation of at least one resin-forming vinyl monomer.
