Composition based on polyamide and additive

Abstract

The present invention relates to a composition comprising: an additive (A) comprising: at least one compound selected from a diamide (A1) obtained by the reaction between at least one diamine and at least one carboxylic acid; a monoamide (A2); or a triamide (A3); optionally a vegetable oil (A4); optionally an optionally functionalized polymer (A5); a polyamide (B) comprising the polycondensation product of an acid component and an amine component, the acid component comprising: at least one fatty acid dimer; at least one aliphatic diacid; optionally at least one chain limiter; the amine component comprising: at least one aliphatic diamine; optionally at least one cycloaliphatic diamine; optionally at least one polyetherdiamine; said composition being characterized in that when the diamide (A1) comprises ethylene bis-stearamide, its mass content is greater than 10% by weight relative to the total weight of the composition;and said composition comprising at least 60% by weight of polyamide (B) relative to the total weight of the composition.
