CA 2270230

The invention concerns a process for preparing compositions containing at least one thermoplastic polymer A and at least one polyamide B by dissolving the thermoplastic polymer A in at least one lactam b and optionally further polyamide-forming monomers b, and subsequent polymerization of the monomers b. The monomers b are polymerized in the presence of between 0.001 and 5 wt % water, relative to the monomers b.

L'invention concerne un procédé de préparation de compositions contenant au moins un polymère thermoplastique A et au moins un polyamide B, par dissolution du polymère thermoplastique A dans au moins un lactame b et éventuellement d'autres monomères b générateur de polyamide, puis par polymérisation des monomères b. Selon ce procédé, les monomères b sont polymérisés en présence de 0,001 à 5 % en poids d'eau par rapport aux monomères b.
