Abstract
Empleo de óxidos metálicos como catalizadores heterogéneos para un procedimiento para la obtención de poliamidas mediante polimerización de lactamas y, en caso dado, de más monómeros formadores de poliamida, en el cual se emplean los óxidos metálicos de tal forma, que permite la separación mecánica de la mezcla de reacción, y se eliminan en el transcurso o después del final de la polimerización de la mezcla de reacción, y llevándose a cabo la polimerización en dos etapas, trabajándose en la primera etapa bajo una presión aumentada, en la cual esta presente la mezcla de reacción con excepción del catalizador heterogéneo de forma monofásica-líquida, y condensándose adicionalmente en la última etapa bajo una presión en el intervalo de 0, 01 hasta 10 x 105 Pa, estando presente el catalizador heterogéneo en una o en ambas etapas, para la reducción del contenido en los compuestos extraíbles en la poliamida obtenida.
