Abstract

Los polioles de polioxialquileno que contienen complejos de cianuro dimetálico o residuos de los mismos, segun se producen durante la preparacion de polioles de polioxialquleno mediante la oxialquilacion catalizada con complejo de cianuro dimetálico de un iniciador hídrico funcionalmente adecuado, son estables sin la eliminacion de catalizador. Los prepolímeros terminados en isocianato preparados a partir de estos polioles tienen una viscosidad sorprendentemente estable con relacion a los prepolímeros similares preparados a partir de polioles que no contienen complejos de cianuro dimetálico o residuos del mismo.
