Patent

CA 2429322

The invention relates to a method for producing polyamides. Said method is characterised in that the polymerisation of starting monomers is carried out in the presence of between 2.3 and 10 mmol - in relation to 1 mol of carboxamide group of the polyamide - of a compound used as a chain transfer agent, comprising a nitrile group and a functional group capable of forming a carboxamide group.

L'invention concerne un procédé de production de polyamide, qui se caractérise en ce qu'on réalise la polymérisation de monomères de départ en présence de 2,3 à 10 mmol, par rapport à 1 mol de groupe carboxamide du polyamide, d'un composé servant de régulateur de chaîne, qui comprend un groupe nitrile et un groupe fonctionnel susceptible de former un groupe carboxamide.
