Abstract

"PROCESSO PARA PRODUZIR POLIAMIDAS". A invenção diz respeito a um método para preparar poliamidas pela reação de pelo menos uma lactama e opcionalmente outros monómeros que formem poliamida com extratos aquosos monoméricos e oligoméricos obtidos quando o polímero é extraído com água na produção de poliamidas, por meio da qual o teor de água da mistura de reação varia de 0,5 a 13 por cento em peso. De acordo com o dito método, a reação é realizada na presença de óxidos metálicos, beta-zeólitos, silicatos em folha ou sílica géis que podem ser dopados como catalisadores heterogêneos. Os catalisadores heterogêneos são usados em uma forma que permita a separação mecânica da mistura de reação e a remoção da mistura de reação durante ou depois da conclusão da polimerização.
