Patent ID: 7014919

Claim:
A composition comprising, by weight, the total being 100%: a semi-crystalline polyamide (A); 5 to 35% of an amorphous polyamide (B) which results from the condensation: of (B1) at least one cycloaliphatic diamine or aliphatic diamine, with at least one cycloaliphatic diacid or aliphatic diacid, at least one of the diamine or diacid units being cycloaliphatic, or (B2) of a cycloaliphatic α,ω-aminocarboxylic acid, or (B3) of a combination of (B1), and (B2), and optionally at least one of condensations (B1), (B2) or (B3) may also employ at least one monomer selected from the group consisting of a α,ω-aminocarboxylic acid or the corresponding lactam, an aliphatic diacid, and an aliphatic diamine; a further polyamide (C), in an amount of up to 40% which is a copolymer containing polyamide blocks and polyether blocks; 0 to 20% of a compatibilizer (D) for (A) and (B); 0 to 40% of modifier (M); with the condition that (C)+(D)+(M) is not more than 50%, and (C) is present, said composition being semi-crystalline, with the proviso that the amorphous polyamide (B) does not contain aromatic units.
