    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.

    摘要: A process, carried out without a diluent or in solution, in more than 2 reaction zones, for the continuous preparation of rubber-modified polymers of vinylaromatics, wherein a monomeric aromatic vinyl compound and an elastomeric polymer, in an amount of from 3 to 16% by weight based on the monomer, are polymerized, in the absence of a free radical initiator, but in the presence of a mercaptan as a chain transfer agent, at from 80.degree. to 180.degree. C. in a first reaction zone, with stirring, up to a maximum monomer conversion, U.sub.max, given by the equationU.sub.max =K-1where K is the amount of rubber in % by weight based on monomer, and, in a second reaction zone, polymerization is continued, with stirring, to a conversion of up to about 50% by weight, after which a chain transfer agent is introduced in an amount of from 0.01 to 0.2% by weight, based on vinyl-aromatic monomer, and polymerization is continued, if appropriate in more than one reaction zone, up to a monomer conversion of less than 85% by weight. The polymer is treated in a devolatilization zone to remove vinyl-aromatic monomer and solvent, if any, and these constituents are recycled to the process. The process produces products which exhibit good gloss coupled with good mechanical properties, and which can be employed for conventional applications.
