Abstract
A process for the manufacture of polyamide is described. Also described, is a process comprising a stage of initial polymerization under pressure starting from monomers and a stage of finishing in the liquid phase at atmospheric pressure. The finishing stage can employ an injection of inert gas along a direction essentially parallel to that of the flow of the liquid reaction stream.
