Abstract:
A molding composition, comprising:at least 50% by weight of a polyamine-polyamide copolymer; wherein the polyamine-polyamine copolymer is obtained from the following monomers: a) from 0.05 to 2.5% by weight of a polyamine having at least 4 nitrogen atoms based on the polyamine-polyamide copolymer, and b) a polyamide-forming monomer selected from the group consisting of a lactam, &ohgr;-aminocarboxylic acid, an equimolar combination of a diamine and a dicarboxylic acid and mixtures thereof; wherein the polyamine-polyamide copolymer has the following properties: a viscosity of at least 5 000 Paâ€¢s at 250Â° C. and at a shear rate of 0.1 l/s; and a viscosity ratio of at least 7 at 250Â° C., when the melt viscosities at shear rates of 0.1 l/s and 100 l/s are compared with one another.
