Abstract
"MéTODO PARA PREPARAR CATALISADORES DE CIANETO METáLICO USANDO SAIS METáLICOS INSOLúVEIS". Preparam-se dispersões de catalisador de cianeto metálico em compostos iniciadores e/ou poliéteres reagindo um composto de cianeto metálico ácido com um sal metálico insolúvel num meio que é um solvente para o composto de cianeto metálico ácido mas não para o sal metálico. A pasta de catalisador resultante pode ser combinada com um iniciador e extraída para formar uma pasta de catalisador/iniciador ou catalisador/poliéter. Usando este método, prepara-se um catalisador de polimerização de óxido de alquileno ativo, e o método de preparação é muito simplificado. Além disso, não é necessário usar um agente complexante orgânico separado na preparação.
