Abstract:
The present invention relates to the use of at least one urea compound of the formula (I), wherexis 1, 2 or 3; R 1 and R 2 are selected from hydrogen, linear C 1 -C 7 -alkyl, branched C 3 -C 10 -alkyl, unsubstituted or substituted C 3 -C 12 -cycloalkyl, unsubstituted or substituted C 3 -C 12 -cycloalkyl-C 1 -C 4 -alkyl, unsubstituted or substituted aryl and unsubstituted or substituted aryl-C 1 -C 4 -alkyl; and Z is selected from C 3 -C 10 -alkanediyl, unsubstituted or substituted arylene, unsubstitutedor substituted arylene-C 1 -C 4 -alkylene-arylene, unsubstituted or substituted heteroarylene, unsubstituted or substituted heteroarylene-C 1 -C 4 -alkylene-heteroarylene, unsubstituted or substituted C 5 -C 8 -cycloalkylene, unsubstituted or substituted C 5 -C 8 -cycloalkylene-C 1 -C 4 -alkylene-C 5 -C 8 -cycloalkylene, unsubstituted or substituted heterocycloalkylene and unsubstituted or substituted heterocycloalkylene-C 1 -C 4 -alkylene-heterocycloalkylene for improving at least one solid state property of a polyamide resin. The solid state property is preferably selected from mechanical properties and gloss.
Abstract:
The invention relates to a polyamide composition (PZ) containing at least one polyamide (P) and at least one additive (A). The invention further relates to the use of said polyamide composition (PZ) in a selective laser sintering process, in an injection molding process for manufacturing molded articles, and in an extrusion process.
