    Abstract: Thermoplastic molding compositions composed of A) a polyamide having amino or carboxy end groups or a mixture of these end groups, B) a mixture composed of at least two graft copolymers, each comprising a rubber as graft base and a graft based on an unsaturated monomer, where these differ at least 5% by weight from one another in their rubber contents, C) a rubber-free copolymer, comprising c1) at least 30% by weight, based on the total weight of all of the units present in C), of units which derive from a vinylaromatic monomer, c2) units which derive from a monomer which comprises a functional group which can react with the end groups of the polyamide A), and c3) units which derive from a monomer which comprises no functional groups which react with the end groups of the polyamide A), and also moreover, if desired, D) a rubber-free matrix polymer, E) a low-molecular-weight compound which comprises a dicarboxylic anhydride group, and F) an additive, or a mixture of various additives.

    Abstract: The present invention relates to a process for preparation of copolymers A) comprising A1) one or more vinylaromatic monomers, A2) one or more vinyl cyanides, and A3) one or more dicarboxylic anhydrides via bulk polymerization or via solution polymerization, an important feature of the invention being that the polymerization is carried out in the presence of from 0.01 to 0.5% by weight of water, based on the total weight of the polymerization mixture. The present invention further relates to the copolymers A), to thermoplastic molding compositions comprising the copolymers A), to the use of the copolymers A) and of the thermoplastic molding compositions, and also to the moldings, foils, fibers, or foams obtainable from the copolymers A) or from the thermoplastic molding compositions.

    Abstract: The present invention relates to thermoplastic molding compositions comprising a mixture of (A) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a methyl methacrylate polymer, (B) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a copolymer obtainable by polymerizing a styrenic monomer and a vinyl cyanide, and (C) from 1 to 40% by weight, based on the sum of components (A), (B) and (C), of a graft copolymer obtainable from (C1) from 60 to 90% by weight, based on (C), of a core obtainable by polymerizing a 1,3-diene and a styrenic monomer, (C2) from 5 to 20% by weight, based on (C), of a first graft shell, and (C3) from 5 to 20% by weight, based on (C), of a second graft shell composed of an alkyl (meth)acrylate polymer, with the proviso that the ratio of (C2) to (C3) is in the range from 2:1 to 1:2.
