    • 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.
    • 用于连续制备乙烯基芳族化合物的橡胶改性聚合物的方法,其中含有单体芳族乙烯基化合物和基于单体的3-30重量%的弹性体聚合物的混合物,具有或不具有溶剂 在存在自由基引发剂的情况下,在作为链转移剂的硫醇存在或不存在下,在80-180℃下,在搅拌下,在两个或更多个等温操作的反应区的级联中聚合 以及一个或多个另外的反应区,其可以等温或以升高的温度曲线操作,使得反应物在第一反应区中的停留时间为35分钟。 获得的聚合物在脱挥发分区域中不含乙烯基芳族单体和任何溶剂。 该产品可用于生产注射成型品。

    • A molding material as based on from 60 to 98% by weight of a hard matrix A comprising polymerized or copolymerized units of at least one vinylaromatic monomer or at least one vinylaromatic monomer and at least one polar comonomer and from 2 to 40% by weight, the percentages in each case being based on the molding material comprising A and B, of a soft phase B formed from a hydrogenated or unhydrogenated block copolymer prepared by anionic polymerization and comprising a vinylaromatic monomer V and a diene D, having at least one random or quasi-random block (V/D) of vinylaromatic monomer and diene and containing from 10 to 80% by weight, based on the soft phase B, of occlusions of matrix material (a) formed during the polymerization of the hard matrix A in the presence of the block rubber, and said molding material is used for the production of films, sheets or moldings.
