Abstract

Se preparan dispersiones de catalizador de cianuro de metal en compuestos iniciadores mediante la precipitacion del catalizador en una fase acuosa, lamezcla de la pasta resultante con el iniciador, y la separacion del agua y otros volátiles. Utilizando este método, se prepara un catalizador de polimerizaciode oxido de alquileno activo, y se simplifica mucho el método de preparacion. Además, no es necesario utilizar un agente complejante orgánico separado en lapreparacion.
