Impact-modified polymer compositions

The invention relates to impact-modified polyamide compositions and molding produced therefrom which are suitable for on-line lacquering, and the production of moldings which have been subjected to on-line lacquering. An impact-modified polyamide composition, comprising (A) 55 to 90 parts by wt. of...

Zusammenfassung:The invention relates to impact-modified polyamide compositions and molding produced therefrom which are suitable for on-line lacquering, and the production of moldings which have been subjected to on-line lacquering. An impact-modified polyamide composition, comprising (A) 55 to 90 parts by wt. of a polyamide, (B) 0.5 to 50 parts by wt. of a graft polymer, (C) 0.1 to 30 parts by wt. of a mineral particle having anisotropic particle geometry, (D) 0 to 50 parts by wt. of thermoplastic polymers as compatibilizer, containing D.1 a vinylaromatic monomer, D.2 at least one monomer chosen from the group consisting of C2 to C12-alkyl methacrylates, C2 to C12-alkyl acrylates, methacrylonitriles and acrylonitriles, and D.3 alpha,beta-unsaturated components comprising dicarboxylic acid anhydrides, and (E) 0 to 30 parts by wt. of vinyl (co)polymer, containing at least one monomer selected from the group consisting of vinylaromatics, vinyl cyanides, (meth)acrylic acid (C1-C8)-alkyl esters, unsaturated carboxylic acids and derivates of unsaturated carboxylic acids, wherein the graft polymer is not based on ethylene-propylene rubbers or rubbers based on ethylene-propylene and non-conjugated dienes as a graft base, and wherein the sum of the parts by weight of all the components being standardized to 100.
