Patent ID: 7312263

Claim:
A thermoplastic polyamide moulding composition containing at least 20% by weight of polyamide 12, related to a total mass of polyamide matrix component, and/or one copolymer with at least 20% by weight polyamide 12 components, related to the total mass of the polyamide matrix component and at least one aprotic compound in amounts of 0.05 to 15.0% by weight related to the total mass of the polyamide matrix component, wherein the thermoplastic polyamide moulding composition is made by hydrolytic polymerization or hydrolytic polycondensation processes, and the at least one aprotic compound is selected from the group consisting of N-alkylated, cyclic carboxylic acid amides with 5 to 7 ring elements, wherein the carboxylic acid amide corresponds to formula I, wherein x is 1 to 3 and R1 an octyl residue, wherein the octyl residue is linear or branched at the nitrogen.
