Abstract
Nuevos prepolímeros terminados en isocianato y proceso para fabricar espumas flexibles de poliuretano a partir de los mismos. Los prepolímeros sepreparan a partir de poliéter-polioles que tienen alto peso equivalente. La composicion depre polímero comprende un aducto que contiene uretano dedifenilmetano diisocianato que en forma opcional contiene oligomeros del mismo que tiene una funcionalidad de isocianato mayor que 2 y de un poliéter-poliol1), que tiene un peso equivalente de2200 -10000, un contenido de oxietileno de 5-30% en peso y una funcionalidad hidroxilo nominal de 2-4, siendo lacantidad de secciones poliéter del 35-70% en peso y 2) 2 a 15% en peso de oligomeros no reaccionados de difenilmetanodiisocianato, d ichos oligomerostienen una funcionalidad de isocianato de por lo menos 3, y/o 1 a 25% en peso de tolueno diisocianato, todas las cantidades son calculadas sobre el pesototal de la composicion, la composicion tiene un contenido deNCO- de 8 a 22% en peso cuando el tolueno diisocianato no está presente y un contenido de NCO-de 8,5 a 26% en peso cuando el tolueno diisocianato está presente. Con las composiciones de prepolímeros se preparan espumas flexibles de poliuretanoquemuestran muy b uenas propiedades, en particular alto rebote de bola y baja deformacion a la compresion. El proceso es grandemente mejorado incluso enausencia de agente reductor de viscosidad.
