Abstract
The present invention relates to a polymer composition comprising at least one polyamide and at least one urea compound of the formula I where x is 1, 2 or 3; Rand Rare selected from hydrogen, linear C-C-alkyl, branched C-C-alkyl, unsubstituted or substituted C-C-cycloalkyl, unsubstituted or substituted C-C-cycloalkyl-C-C-alkyl, unsubstituted or substituted aryl and unsubstituted or substituted aryl-C-C-alkyl; and Z is selected from C-C-alkanediyl, unsubstituted or substituted arylene, unsubstituted or substituted aryl unsubstituted or substituted ene-C-C-alkylene-arylene, unsubstituted or substituted heteroarylene, unsubstituted or substituted heteroarylene-C-C-alkylene-heteroarylene, unsubstituted or substituted C-C-cycloalkylene, C-C-cycloalkylene-C-C-alkylene-C-C-cycloalkylene, unsubstituted or substituted heterocycloalkylene and heterocycloalkylene-C-C-alkylene-heterocycloalkylene. This urea compound is used for improving the optical properties of the polyamide polymer composition. The present invention also relates to shaped articles obtained from said composition and to novel urea compounds.
