Abstract
The present invention relates to thermoplastic polyamides (PA) comprising recurring units derived from a PFPE dicarboxylic acid (PFPA-DA) or a PFPE diamine (PFPE-NN) in a defined weight amount with respect to other units derived from the other monomers used in the course of polymerization. Polyamides (PA) are endowed with improved surface properties, chemical resistance and reduced brittleness and do not require the addiction of impact modifiers.
