Abstract
"PROCESSO PARA REDUZIR O TEOR DE EXTRAìVEIS DE POLIAMIDAS EM UM PROCESSO PARA PRODUZIR POLIAMIDAS, E, óXIDOS METáLICOS PARA USO COMO CATALISADORES HETEROGêNEOS EM UM PROCESSO PARA PRODUZIR POLIAMIDAS". A invenção diz respeito ao uso de óxidos de metal como catalisadores heterogêneos em um processo para a produção de poliamidas por polimerização de lactamas, e possivelmente de outros monómeros que formam poliamidas. Em acordo ao dito processo, os óxidos de metal são utilizados em uma forma que permita sua separação mecânica da mistura de reação e durante ou no término da polimerização, são separados da mistura de reação de modo que reduza o teor dos compostos extraíveis no poliamida obtido desse modo.
