Abstract

Polioxipropilén polioles poliméricos catalizados por CDM que exhiben una amplitud de procesamiento similar a los copolímeros análogos catalizados porbases y análogos de homo-polioxipropileno son preparados por oxialquilacion con una mezcla deoxid o de propileno y oxido de etileno de forma que en el reactorde oxialquilacion se mantiene un contenido finito de oxido de etileno durante la parte substancial de la oxialquilacion, y el polioxipropilén poliol tieneporciones de oxietilenodistribuid as aleatoriamente que constituyen el 1,5% en peso o más del poliol prodido. Los polioles de copolímeros de bloque conbloques externos que contienen menor contenido de oxietileno que los bloques internos y composicionesbicomposicionales que conti enen polioles discretosmultimodales y disímil optativamente se producen por el agregado continuo de un proceso iniciador y son utiles como polioles que exhiben mayor amplitud deproceso.
