Patent

CA 2418845

The invention concerns copolyamides obtained by using multifunctional monomers. It consists in using a 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 particularly high viscosity copolyamides. The invention also concerns compositions based on said copolyamides.

L'invention concerne des copolyamides obtenus par utilisation de monomères multifonctionnels. Elle met en oeuvre au moins un monomère multifonctionnel comprenant au moins trois fonctions réactives et au moins un autre monomère multifonctionnel, en quantités telles que les concentrations en groupements terminaux soient équilibrées. Les copolyamides sont plus particulièrement des copolyamides de viscosité élevée. L'invention concerne également des compositions à base de ces copolyamides.
