Abstract:
1. A polyamide obtained by the polycondensation of a mixture of: a) monomers of the following general formula (I): b) monomers of the following general formulae (IIa) and (IIb):  and c) monomers of the following general formula (III): in which: R A is a covalent bond or an aliphatic hydrocarbon radical comprising 1 to 6 carbon atoms, Z is a primary amine radical or a carboxyl group, R X is a carboxyl radical or a primary amine radical; and Y is a primary amine radical when X is a carboxyl radical, or Y is a carboxyl radical when X is a primary amine radical, m is an integer ranging from 3 to 8, the molar concentration of the monomers of formula (I) in the mixture of monomers of general formulae (I), (IIa) and (IIb) being from 0.01% to 1%, and the molar ratio of the monomers of formula (I) to the monomers of formula (III) being from 0.01 to 0.4, and the molar concentration of monomers of formula (III) is from 0.1% to 2% in the mixture of monomers (III), (IIa), and (IIb).
