VISCOELASTIC POLYURETHANE FOAMS THAT INCLUDE OLIGOMERIC NATURAL OIL POLYOLES
Реферат: Se describen espumas viscoelásticas de poliuretano que comprenden un poliol oligomérico de aceite natural y un poliol derivado de petroleo. Las espumas viscoelásticas se forman mediante la reaccion de un poliisocianato con una composicion de hidrogeno activo que comprende el poliol oligomérico de aceite natural y poliol derivado de petroleo. Viscoelastic polyurethane foams comprising an oligomeric natural oil polyol and a petroleum derived polyol are described. Viscoelastic foams are formed by reacting a polyisocyanate with an active hydrogen composition comprising the oligomeric natural oil polyol and petroleum-derived polyol.
