Transparent polyamide molding composition with good processing flow properties achieved without strength loss contains as additive a graft copolymer made from a branched or dendrimeric polyamine and polyamide-forming monomers

摘要

A molding composition comprises (by wt.) (A) a transparent polyamide (50-99%) together with (B) a graft copolymer (1-50%) made from (i) a branched polyamine with 4 or more N atoms and a number-average mol. wt.(Mn) =146 and (ii) polyamide-forming monomers comprising lactams, omega -aminocarboxylic acids and/or equimolar combinations of diamines and dicarboxylic acids.
