Abstract
Derivados de poliuretano que contienen cadenas poliméricas de base silicio. Estos derivados contienen una cadena polimérica de base silicio junto con, opcionalmente, una cadena polimérica de base carbono. Estos derivados pueden obtenerse haciendo reaccionar un poliisocianato con un compuesto polihidroxilado de base silicio junto con, opcionalmente, un compuesto polihidroxilado de base carbono en presencia de un catalizador. Los derivados de poliuretano obtenidos pueden convertirse en las espumas correspondientes poniéndoles en contacto con un espumante. Estas espumas tienen una mayor resistencia a la combustión y no requieren la adición de cargas ignifugantes. Estas espumas son adecuadas para fabricar colchones, almohadas y almohadillas para asientos.
