    摘要： A thermoplastic moulding composition with improved flow properties being workable without difficulty by extrusion, injection moulding or blow moulding and resulting in colorless, transparent products with a smooth, glossy surface, comprising a mixture of(A)90 to 99.9% by weight of a polymer with a K-value of from 50 to 80, as measured at a temperature of 25.degree. C. in dimethyl formamide on a 0.5% by weight solution, which contains at least 50% by weight of acrylonitrile or methacrylonitrile or a mixture thereof in polymerized or grafted form, and(B)0.1 to 10% by weight of a statistical copolymer of copolymerized units of65 to 85% by weight of at least one acrylic acid alkyl ester with 1 to 8 carbon atoms in the alcohol component, and15 to 35% by weight of styrene,The copolymer B having an intrinsic viscosity [.eta.] of from 2.9 to 13.0 dl/g, as measured at 25.degree. C. in tetrahydrofuran.
