摘要： The present invention relates to a copolyamide comprising at least two units and corresponding to the following general formula: A/(diamine).(Cw diacid), in which: the diamine is a cycloaliphatic diamine, w represents the number of carbon atoms of the diacid, A is chosen from a unit obtained from an amino acid or from a lactam and a unit corresponding to the formula (Cx diamine).(Cy diacid), with x representing the number of carbon atoms of the diamine and y representing the number of carbon atoms of the diacid, and in which at least one of the monomers chosen from A and the Cw diacid is obtained, in all or part, from renewable starting materials according to Standard ASTM D6866. The invention also relates to a composition comprising this copolyamide and to the use of this copolyamide and of such a composition.
