1. A thermoplastic polyamide moulding composition consisting of:
(A) 30-99.9 percent by weight of:
(A1) 20-100 percent by weight of at least one aliphatic semicrystalline polyamide based on acyclic dicarboxylic acids and on acyclic diamines selected from PA612, PA614, or PA616; and
(A2) 0-80 percent by weight, of a polyamide selected from the group consisting of at least one amorphous semiaromatic polyamide, at least one cycloaliphatic polyamide, or a mixture thereof,
wherein a percentage by weight of components (A1) and (A2) together provide 100% by weight of component (A);
(B) 0.1-5.0 percent by weight of at least one polyethyleneimine (PEI);
(C) 5.0-60 percent by weight of fillers and/or reinforcing materials;
(D) 0-5.0 percent by weight of additives;
where the entirety of (A)-(D) provides 100% of the thermoplastic polyamide moulding composition.
