Abstract

''POLIAMIDAS, E, PROCESSO PARA A PRODUçãO DAS MESMAS". A presente invenção descreve um processo para produção de poliamidas pela polimerização de lactamas na presença de óxidos de metal como catalisadores heterogêneos. De acordo com a invenção, os óxidos de metal são colocados no interior de um molde que permite a separação mecânica da mistura de reação e são removidos da mistura de reação durante ou após a conclusão da polimerização.
