Beschreibung
Zusammenfassung:	The composite includes a coupling layer comprising a graft copolymer from: (a) a polyamine with at least 4 nitrogen atoms and a number-average molecular weight (Mn) of at least 146; and (b) polyamide-forming monomers (lactams, omega -amino-acids and/or equimol. combinations of diamines and dicarboxylic acids). A thermoplastic multilayer composite comprises layers (I) and (II) of different thermoplastic moulding materials and an interlayer (III) of a coupling agent. At least 5 wt% of (III) consists of a graft copolymer derived from: (a) 0.5-25 wt% (based on the copolymer) of a polyamine with at least 4 nitrogen atoms and a Mn of at least 146; and (b) polyamide-forming monomers selected from lactams, omega -aminocarboxylic acids or equimolar combinations of diamines and dicarboxylic acids. An Independent claim is also included for moulding materials containing: (A) 5-60 parts by weight (pts. wt.) of a graft copolymer as above; (B) 10-85 pts. wt. of a polyamide; (C) 10-85 pts. wt. of a polyester; and (D) not more than 40 wt% (based on A + B + C) of an impact-modifying rubber and/or conventional auxiliary substances or additives.
