Abstract

"MéTODO PARA PREPARAR CATALISADORES DE CIANETO METáLICO USANDO MATERIAIS ZERO VALENTES". Preparam-se dispersões de catalisador de cianeto metálico em compostos iniciadores e/ou poliéteres reagindo um composto de cianeto metálico ácido com um metal zero valente num meio que seja um solvente para o composto de cianeto metálico ácido. A pasta de catalisador resultante pode ser combinada com um iniciador e/ou um poliéter e extraída para formar uma pasta de catalisador/iniciador ou de 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 em separado na preparação.
