Abstract

Un proceso para la preparación de poliamidas provenientes de almenos una lactama con o sin monómeros adicionales y aditivos de costumbre y llenadores, que comprendea) Concentrar el extracto de agua de lavado de la extracción de poliamida a un contenido de extraíbles de no más del 85% en peso, b) Ajustar el contenido de agua del concentrado resultante a 0,5 a 13% en peso por la adición de lactama fresca, c) Someter la mezcla resultante a polimerización bajo condiciones de formación de poliamida, d) Efectuar al menos una expansión adiabática durante la polimerización para reducir el contenido de agua.
