Abstract:
1. Thermoplastic copolyamide resulting from the reaction between at least one polyfunctional monomer satisfying the following general formula I: in which: n is an integer greater than or equal to 2, R R is a linear or branched aliphatic radical, a cycloaliphatic radical, an aromatic radical, or a polymeric chain, A represents an amine or amine salt functional group, or an acid, ester, acid halide or amide functional group, B represents an amine or amine salt functional group when A is an acid, ester, acid halide or amide functional group, or B is an acid, ester, acid halide or amide function group when A is an amine or amine salt functional group, and at least one bifunctional monomer of the following formulae II to IV, and optionally, a monofunctional monomer of the following formulae V or VI; or a prepolymer obtained from at least one bifunctional monomer of the following formulae II to IV and, optionally, at least one monofunctional monomer of the following formulae V or VI, the bifunctional monomers satisfying the following general formulae:  and/or the corresponding lactams of (IV) the monofunctional monomers satisfying the following general formulae:  and/or  in which A R R
