Abstract

Un prepolímero de poliuretano terminado con isocianato que comprende el producto de reaccion de un poliisocianato y una composicion de poliol que consiste esencialmente de un poliol de poliéster de peso equivalente de 350-2000 y un poliol debajo peso molecular de peso molecular de 62 a <300, y una relacion equivalente de poliol de bajo peso molecular a poliol de poliéster de 0.25-2.7:1. Un elastomero de poliuretano-urea que tiene buenas propiedades dinámicas puede prepararse haciendo reaccionar el prepolímero terminado con isocianato con un expansor de cadena de amina aromática a una relacion equivalente de 0.9:1.1:1.
