Abstract

Patente de Invenção: <B>"CATALISADORES DE CIANETO DE METAL DUPLO CONTENDO POLIéSTER PARA A PREPARAçãO DE POLIETERPOLIóIS"<D>. A invenção refere-se a novos catalisadores de cianeto de metal duplo (CMD) aperfeiçoados para a preparação de polieterpolióis, por poliadição de óxidos de alquileno a compostos de iniciador apresentando átomos de hidrogênio ativos, sendo que o catalisador contém um composto de cianeto de metal duplo, um ligante de complexo orgânico e 5-80% em peso, com relação à quantidade do catalisador, de um poliéster. Os novos catalisadores aperfeiçoados possuem tempos de indução nitidamente encurtados para a preparação de polieterpoliol e, simultaneamente, atividade fortemente elevada.
