Abstract

La presente se refiere a un procedimiento de obtención de polioléteres de alta pureza y bajo olor, con muy bajos niveles de restos catalíticos, mediante reacciones de poliadición de óxidos de alqueno que contienen hidrógenos activos, en presencia de cianuros metálicos dobles como catalizadores. El procedimiento se caracteriza por llevar a cabo la reacción de poliadición en presencia de sepiolitas y/o por el tratamiento posterior con sepiolitas de los polioléteres producidos con cianuros metálicos dobles en ausencia de sepiolitas.
