    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 process for the continuous preparation of rubber-modified polymers of vinyl-aromatics, wherein a mixture which contains a monomeric aromatic vinyl compound and from 3 to 30% by weight, based on the monomer, of an elastomeric polymer, with or without a solvent, is polymerized, in the presence of a free radical initiator and in the presence or absence of a mercaptan as chain transfer agent, at from 80.degree. to 180.degree. C., with stirring, in a cascade of two or more isothermally operated reaction zones and of one or more additional reaction zones which can be operated isothermally or with a rising temperature profile in such a way that the residence time of the reactants in the first reaction zone is .ltoreq.35 minutes. The polymer obtained is freed from vinyl-aromatic monomer, and from any solvent, in a devolatilization zone. The product is useful for the production of injection moldings.

    摘要： Thermoplastic molding materials which contain a copolymer which has been made impact-resistant with a rubber. The copolymer is produced by polymerizing a mixture of a monovinyl-aromatic compound and an acrylic acid derivative or methacrylic acid derivative in the presence of a rubber. The folding materials contain a specific proportion of soft component. The diameter of the particles of the soft component, and the swelling index of the soft component, lie within a specific range, and the tensile strength of the molding material is higher than the yield strength.
