Abstract:
A molding composition, comprising:I. from 0.1 to less than 5 parts by weight of a polyamine-polyamide graft copolymer which is prepared using the following monomers: a) from 0.5 to 25% by weight, based on the graft copolymer, of a branched polyamine having at least 4 nitrogen atoms and a number-average molar mass Mn of at least 146 g/mol, and b) polyamide-forming monomers selected from the group consisting of lactams, &ohgr;-aminocarboxylic acids, and equimolar combinations of diamine and dicarboxylic acid; and II. from more than 95 to 99.9 parts by weight of a thermoplastic polyester, where the total of the parts by weight of I and II is 100; wherein said branched polyamine is selected from the group consisting of branched polyethyleneimines having the following distribution of amino groups; from 25 to 46% of primary amino groups, from 30 to 45% of secondary amino groups, and from 16 to 40% of tertiary amino groups.
