Xylylene-based polyamides and their use

Polyamide composition comprises a polyamide in the form of a homo-polyamide or a statistical copolyamide based on m-xylylene diamine and a diacid in the form of a dimeric fatty acid, and aliphatic or cycloaliphatic diamines and/or aliphatic or cycloaliphatic diacids, where the portion of m-xylylene diamine is 50-100 mol.%, the portion of dimeric fatty acid is 30-100 mol.%, and the portion of further aliphatic or cycloaliphatic diamines is 0-50 mol.%, and the portion of further aliphatic or cycloaliphatic diacid is 0-70 mol.%. Polyamide composition comprises at least one polyamide in the form of a homo-polyamide or a statistical copolyamide based on m-xylylene diamine and a diacid in the form of a dimeric fatty acid, and optionally further aliphatic or cycloaliphatic diamines and/or aliphatic or cycloaliphatic diacids, where the portion of m-xylylene diamine is 50-100 mol.%, the portion of dimeric fatty acid is 30-100 mol.%, the portion of further aliphatic or cycloaliphatic diamines is 0-50 mol.%, and the portion of further aliphatic or cycloaliphatic diacid is 0-70 mol.%, provided that the diamine and diacid are complement to 100 mol.%, and the polyamide is not based on lactams and/or aromatic monomers and is free of polyether and/or polyester blocks. An independent claim is included for a mixture, preferably in the form of dry blends or compounds comprising the polyamide composition and further one or more polymer consisting of polyamide 6, polyamide 66, polyamide 69, polyamide 610, polyamide 612, polyamide 614, polyamide 618, polyamide 1010, polyamide 6/66, polyamide 6/12, polyamide 11, polyamide 12, polyamide 912, polyamide 1212, polyamide m-xylylene diamine 6/m-xylylene diisocyanate, polyamide 6I/6T, polyesteramide or polyetheramide.
