Abstract

PROCEDIMIENTO PARA PREPARAR UN PREPOLIMERO DE URETANO. COMPRENDE: A) INTRODUCIR DOS INTERMEDIARIOS URETANICOS EN UN RECIPIENTE; B) AÑADIR UNA CANTIDAD EFICAZ DE UN POLIISOCIANATO DE FORMULA R(N=C=O)N A LA MEZCLA DE INTERMEDIARIOS URETANICOS; C) HACER REACCIONAR A LOS INTERMEDIARIOS URETANICOS CON EL POLIISOCIANATO, ENTRE 25 Y 150GC, PARA FORMAR EL PREPOLIMERO DE URETANO; D) CURAR AL PREPOLIMERO DE URETANO CON UN AGENTE EXTENDEDOR DE CADENA Y ENTRE 30 Y 100GC. EL INTERMEDIARIO URETANICO TIENE DOS GRUPOS FINALES SELECCIONADOS ENTRE HIDROXILO, Y AMINA COMO POLI(OXIETILENO)DIOL Y POLI(OXIPROPILENO)DIOL Y UN GRUPO ETER RECURRENTE (OR) Y EL AGENTE EXTENDEDOR DE LA CADENA TIENE UN POLIOL DE C 2 A 12 Y UNA AMINA ANALOGA DE C 2 A 12. SIENDO: R, UN RADICAL ALIFATICO O CICLOALIFATICO DE C 2 A 20 Y N, 2 O 3. SE UTILIZA EN CUBIERTAS DE NEUMATICOS.
