Abstract

Un método de reducción del contenido de extraibles de poliamidas obtenidas por medio de la polimerización de lactamas y opcionalmente monómeros formadores de poliamidas adicionales mediante catálisis heterogénea con óxidos de metal caracterizado porque los óxidos metálicos son utilizados en una forma que permite la remoción mecánica de la mezcla de reacción, y cuyos óxidos metálicos son removidos de la mezcla de reacción durante o después de la polimerización.
