    Abstract: A thermoplastic molding material comprises copolymers I and II. Copolymer I is a high-impact (graft) copolymer which is derived from a monovinyl-aromatic monomer and a polymer or copolymer predominantly containing polymerized 1,3-diene units, and is present in a proportion of 0.1-1.0% by weight, based on the molding material. Copolymer II is a block copolymer with star-shaped branching, ie. a radial block copolymer, having an average of more than two branches per molecule. It is substantially derived from 55-80% by weight of a monovinyl-aromatic monomer and 20-45% by weight of a 1,3-diene monomer. The molding material may contain conventional assistants and is used for the production of blown film.
