Abstract: Thermoplastic molding materials which have high gloss and are readily colored and comprise a first graft copolymer A of an elastomeric, crosslinked acrylate polymer as the graft base and a graft shell made from a vinyl-aromatic monomer and a polar, copolymerizable, ethylenically unsaturated monomer, and a second separately prepared graft copolymer B of an elastomeric crosslinked acrylate polymer as the graft base, which is different from that in A and has a larger mean particle diameter than the graft base of copolymer A, having a first graft shell of a vinyl-aromatic monomer and a second graft shell of a mixture of a vinyl aromatic monomer and a polar-copolymerizable, ethylenically unsaturated monomer, and a hard matrix C.

Abstract: Thermoplastic polyester molding materials essentially contain(A) from 20 to 89% by weight of one or more aliphatic polyesters of an aromatic dicarboxylic acid,(B) from 10 to 79% by weight of one or more aromatic polycarbonates and(C) from 1 to 40% by weight of an elastomer or of a mixture of elastomers consisting ofCA from 5 to 100% by weight of an elastomeric graft polymer composed ofCA1 not less than 50% by weight of a grafting base having a glass transition temperature T.sub.g of less than -20.degree. C.,CA2 from 5 to 20% by weight of a first graft shell consisting of a mixture of a C.sub.1 -C.sub.8 -alkyl ester of acrylic acid and a vinylaromatic in a weight ratio of from 5:95 to 70:30 andCA3 from 10 to 30% by weight of a second graft shell consisting of one or more polymers having a glass transition temperature T.sub.g above 20.degree. C.

Abstract: Aqueous dispersions of copolymers having a glass transition temperature of not more than -45.degree. C. and a K value greater than 80 consist of not less than 80% by weight of acrylates of alkanols of 8 to 12 carbon atoms, from 1 to 4% by weight of .alpha.,.beta.- monoolefinically unsaturated carboxylic acids and/or their amide derivatives and from 0.1 to 3% by weight of .alpha.-methylstyrene, and are used for the production of self-adhesive structures having good tack at as low as -40.degree. C.
