Abstract

ESTA INVENCION SE REFIERE A MEZCLAS DE POLIMETILEN POLI(FENILISOCIANATOS) CON EPOXIDOS. LA ADICION DEL EPOXIDO ESTABILIZA LA REACTIVIDAD DE LAS MEZCLAS DE POLIISOCIANATO, DE FORMA QUE ESTA YA NO DEPENDE MAS DE LA ACIDEZ. AHORA ES POSIBLE FORMAR POLIURETANOS A PARTIR DE ESTAS MEZCLAS BASADAS EN POLIMETILEN POLI(FENILISOCIANATOS), NECESITANDOSE MENOS CATALIZADOR.
