Abstract

<B>Patente de Invenção: ''CATALISADOR DE POLIMERIZAçãO E PROCESSO DE POLIMERIZAçãO''<D> Descreve-se catalisador de polimerização à base de fosfazeno linear da fórmula geral em que cada R representa um hidrocarbono C~ 1-10~ ou em que dois grupos R em um átomo de N formam com o átomo de N um grupo heterocíclico, X representa um ânion e n é de 1 a 10, bem como processo para sua preparação mediante reação de um composto de fosfonitrilo linear com uma amina secundária ou um sal de uma amina secundária ou uma amida de metal do mesmo para formar um material de fosfazeno aminado, seguido por um reação de troca de íon substituindo o ânion por um nucleófilo.
