摘要： 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.

摘要： A transparent thermoplastic molding material contains, based on A+B,A: from 5 to 95% by weight of polystyrene andB; from 95 to 5% by weight of a nonelastomeric star block copolymer which is composed of, based on B, b.sub.1 from 60 to 95% by weight of styrene and b.sub.2 from 5 to 40% by weight of one or more conjugated dienes of 4 or 5 carbon atoms and is prepared in a conventional manner by sequential anionic polymerization using one or more organolithium compounds as an initiator and in the presence of a solvent with subsequent coupling.In this process, component A is produced by conventional anionic polymerization using one or more organolithium compounds in the presence of an organic solvent.The molding material is prepared by mixing the components A and B, with or without C, in a conventional manner and is used for the production of moldings.
