Abstract

Patente de Invenção: <B>"CATALISADORES DE CIANETO BIMETáLICO PARA A PREPARAçãO DE POLIETERPOLIóIS"<D>. A invenção refere-se a novos catalisadores de cianeto bimetálico (DMC), para a preparação de polieterpolióis por poliadição de óxidos de alquileno a compostos iniciadores, que apresentam átomos de hidrogênio, sendo que o catalisador contém a) compostos de cianeto bimetálico, b) ligantes complexadores orgânicos, diferentes de c) e c) glicosídio. Os catalisadores de acordo com a invenção possuem uma atividade fortemente aumentada na preparação de polieterpolióis.
