Abstract

Las dispersiones de catalizador de cianuro de metal en compuestos iniciadores se preparan al precipitar el catalizador en un compuesto orgánico inerte, mezclar la pasta resultante con el iniciador y despojar del compuesto orgánico inerte. Utilizando este método, se prepara un catalizador de polirnerizacion de oxido de alquileno activo, y el método de preparacion se simplifica grandemente. Además, no es necesario utilizar un agente formador de complejos orgánico por separado en la preparacion.
