Abstract

Procedimiento para la obtención de poliamidas a partir de al menos una lactama y, en caso dado, otros monómeros, y aditivos y cargas habituales, caracterizado porque a) se concentra el agua de extracción de la extracción de poliamida hasta un contenido de extracto de como máximo 85 % en peso, b) se ajusta el contenido de agua del concentrado obtenido mediante adición de lactama fresca hasta 0,5 a 13 % en peso, c) se somete la mezcla obtenida a la polimerización en condiciones de formación de poliamidas y d) se realiza durante la polimerización al menos una expansión adiabática para la reducción del contenido de agua.
