The amount of polymer A is 1 to 25 percent by weight based on the weight of A+B+C. It has a glass transition temperature, Tg, of less than 0.degree. C. and an average particle size of 200 to 750 nanometers (d.sub.50 value of the integral mass distribution) and is composed of: 50 to 99.9 percent by weight of at least one alkylacrylate with 1 to 8 carbon atoms in the alkyl radical and 0.1 to 5 percent by weight of a polyfunctional monomer which has a crosslinking action. Grafting shell B represents 5 to 40 percent by weight based on A+B+C and is composed of at least one of the monomers of the group of(b.sub.1) vinylaromatic monomers, and(b.sub.2) the ethylenically unsaturated monomers.Grafting shell B is prepared in two stages with 30 to 70 percent by weight of the monomers b.sub.1 being used in the first stage, and 30 to 70 percent by weight of a mixture of monomers b.sub.1 and b.sub.2 in a weight ratio of 90:10 to 60:40 being used in the second stage.Copolymer C is added in an amount of 35 to 94 percent by weight based on A+B+C and consists of a vinylaromatic monomer and an ethylenically unsaturated monomer.The molding material may contain commonly used additives in effective amounts and is used for the preparation of molded parts.

摘要: Impact-resistant thermoplastic molding compositions having a hard component comprising a styrene/acrylonitrile copolymer and a soft component comprising a graft copolymer of styrene and acrylonitrile on a rubbery polymer containing butadiene. The rubbery polymer serving as base for the graft copolymer is produced by polymerization or the monomer of monomers forming said polymer in aqueous emulsion and in the presence of a small amount of an alkanol of from 1 to 4 carbon atoms. The compositions have improved color and color stability and may be processed by conventional methods to form shaped articles.
