Abstract

Un método para preparar un poliol de reciclado, el cual se obtiene a partir de la glicolisis de los poliuretanos y/o poliurea-poliuretanos, y comprende hacer reaccionar los desechos de poliuretanos y/o poliurea-poliuretanos con un compuesto de cadena corta que contiene cuando menos 2 grupos de OH; en la presencia de un catalizador y en mezcla con un carbonato cíclico. Este método produce un poliol de reciclado que tiene un contenido bajo en aminas aromáticas primarias, este poliol se puede usar para producir poliuretanos, poliurea-poliuretanos o poliisocianuratos tanto celulares como no celulares.
