Abstract

Se proporciona ahora una composicion de poliol que contiene un poliol que contiene enlaces de poliéster y un numero de peso molecular promedio de 400 o más, y cuando menos aproximadamente 8 php de un polímero surfactante que contiene silicon. Un hidrocarburo C4-C7 alifático o cicloalifático se mezcla en la composicion de polioles o bien al momento de la formacion de espumas, o bien se mezcla en un isocianato o bien ambas cosas. La composicion de polioles se emplea para preparar espuma rígida de células cerradas basada en poliisocianato mediante la reaccion de un isocianato orgánico y la composicion de polioles en presencia de un agente de dispersion de hidrocarburo C4-C7 alifático o cicloalifático. Se presenta también el método para preparar una espuma rígida de células cerradas basada en poliisocianato empleando el poliol de la presente invencion.
