Abstract

Procedimiento para la preparación de poliamidas porpolimerización de lactamas en presencia de óxidos metálicos como catalizadores heterogéneos, caracterizado por - separar mecánicamente los óxidos metálicos de la mezcla de reacción y; - retirar dichos óxidos metálicos durante el transcurso o al final de la polimerización. Procedimiento de acuerdo con la reivindicación 1, caracterizado porque en dicho paso de separar los catalizadores de óxido metálico son utilizados en forma de granulados, hebras, lechos fijos o cuerpos de relleno o insertos recubiertos con catalizador.
