摘要：
The invention concerns copolyamides obtained by using multifunctional monomers. It consists in using at least one multifunctional monomer comprising at least three reactive functions and at least another multifunctional monomer, in amounts such that the terminal group concentrations are balanced. The copolyamides are more particularly high viscosity copolyamides. The invention also concerns compositions based on said copolyamides.
