Abstract:
A thermoplastic molding composition comprising:A) 5 to 95 wt. % of a thermoplastic polymer selected from at least one of thermoplastic homopolymers, thermoplastic copolymers and thermoplastic terpolymers, said thermoplastic polymer being prepared from at least one monomer selected from styrene, &agr;-methylstyrene, nuclear-substituted styrene, methyl methacrylate, acrylonitrile, methyacrylonitrile, maleic anhydride and N-substituted maleimide; B) 5 to 95 wt. % of at least one graft polymer prepared from, B.1) 5 to 90 parts by weight of at least one monomer selected from styrene, &agr;-methylstyrene, nuclear-substituted styrene, methyl methacrylate, acrylonitrile, methyacrylonitrile, maleic anhydride and N-substituted maleimide, and B.2) 10 to 95 parts by weight of at least one rubber having a glass transition temperature of &lE;10Â° C.; and C) 0.05 to 10 parts by weight, based on 100 parts of A+B, of component (III) and at least two further components selected from components (I), (II) and (IV), wherein component (I) has at least one structural unit represented by the following formula: â€ƒM being a metal, and n being the valency of the metal M, component (II) has at least one structural unit represented by: â€ƒand at least one structural unit represented by: â€ƒcomponent (III) has at least one structural unit represented by the following formula: â€ƒand component (IV) is a compound different from those of components (I), (II) and (III), and is selected from at least one of: paraffin oils; hydrocarbon waxes; polystyrene produced by using C8-C18 alkyl mercaptans as molecular weight regulators, and having a mean weight averaged molecular weight between 2000 and 15,000; styrene/acrylonitrile copolymer produced by using C8-C18 alkyl mercaptans as molecular weight regulators, and having a mean weight averaged molecular weight of between 2000 and 15,000; &agr;-methylstyrene/acrylonitrile copolymer produced by using C8-C18 alkyl mercaptans as molecular weight regulators, and having a mean weight averaged molecular weight of between 2000 and 15,000; and poly(methyl methacrylate) produced by using C8-C18 alkyl mercaptans as molecular weight regulators, and having a mean weight averaged molecular weight of between 2000 and 15,000; C6-C32 alkanols; and C6-C32 alkenols.
