Abstract: Preparation of polyamides from a lactam(s) and optionally other monomers and additives and fillers comprises: (a) concentrating the extraction water from the extraction of polyamide to at most 85%; (b) adjusting the water content to 0.5-13 wt.% by adding fresh lactam; (c) exposing to polyamide forming conditions; and (d) adiabatically expanding during polymerization to reduce the water content.
