ABS moulding compounds with improved yield stress

Thermoplastic molding compounds, containing

• A) 5-95 weight % of a thermoplastic homo-, co- or terpolymer of styrene, alpha-methylstyrene, ring-substituted styrene, methyl methacrylate, acrylonitrile, methacrylonitrile, maleic anhydride, N-substituted maleimide, vinyl acetate or mixtures thereof,
• B) 5-95 weight % of a graft polymer of
• B.1) 5-90 parts by weight of styrene, alpha-methylstyrene, ring-substituted styrene, methyl methacrylate, acrylonitrile, methacrylonitrile, maleic anhydride, N-substituted maleimide, vinyl acetate or mixtures thereof graft polymerized onto
• B.2) 95-10 parts by weight of a polybutadiene, butadiene styrene copolymers, butadiene acrylonitrile copolymers, polyisoprene or alkyl acrylate rubber
• C) 0.5-4 parts by weight per 100 parts by weight of A+B of a grafted product of a mixture of styrene and acrylonitrile graft polymerized onto an ethylenepropylene-diene terpolymer rubber with a rubber content of 20-60 weight %.
