Abstract
Se modifican poliisocianatos aromáticos mediante reacción con 0,1 hasta 10, preferentemente 2 a 7 en peso (referido al poliisocianato) de un poliéteralcohol con unpeso molecular de 206 hasta 948, obtenible mediante reacción de óxidos de alquileno con hidrocarburos con 6 a 30 átomos de carbono, preferentemente con 8 a 20 átomos de carbono, que presentan de 1 a 3 átomos de dH activos, y se emplean para la obtención de materiales sintéticos espumados duros de poliuretano.
