Abstract

La invencion se refiere a un proceso para la preparacion de polioles de polieter por medio de la catalisis del cianuro de metal doble (DMC) en la que la fase de la induccion se reduce notablemente. Por una distribucion continua de un oxido de alquileno en la mezcla catalitica iniciadora es posible lograr una reduccion sustancial de la fase de induccion en comparacion con la activacion en forma discontinua.
