Abstract

Patente de Invenção: <B>"CATALISADORES DE CIANETO DE METAL DUPLO APERFEIçOADOS PARA A PREPARAçãO DE POLIETERPOLIóIS".<D> A invenção refere-se a novos catalisadores de cianeto de metal duplo (DMC) aperfeiçoados para a preparação de polieterpolióis mediante poliadição de óxidos de alquileno com compostos de partida que apresentam átomos de hidrogênio ativos, sendo que o catalizador contém um composto de cianeto de metal duplo, um ligante de complexo orgânico e 5 até 80 %, em peso, com relação à quantidade do catalisador, de um poliéter de óxido de etileno com peso molecular de média numérica maior do que 500. Os novos catalisadores aperfeiçoados possuem atividade fortemente aumentada para a preparação do polieterpoliol.
