Abstract

Se proveen polioles de polioxialquileno que contienen más de 25 hasta 1.000 ppm de uno o más complejos de cianuro dimetálicos o residuos de los mismos,basados en el peso del poliol. Los polioles que tienen esas concentraciones de catalizadores ores iduos de catalizador tienen una estabilidad alalmacenamiento mejorada, estabilidad que es también obtenida en concentraciones de catalizador o residuos de catalizador tan bajas como 10 ppm siempre que unantioxidante esté incluído en el poliol.Los pr epolímeros terminados con isocianato preparados a partir de esos polioles tienen una tendencia reducidaa incrementar la viscosidad en almacenamiento. Los polímeros de poliuretano derivados de polioles y los prepolímeros también sonprovist os.
