Abstract
METODO DE PREPARACION DE ELASTOMEROS DE URETANO. CONSISTE EN MEZCLAR UN PREPOLIMERO DE URETANO, QUE CONTIENE POLIISOCIANATO LIBRE DE FORMULA R(N=C=O)N, EN LA QUE R PUEDE SER UNO DE VARIOS TIPOS DE RADICALES Y N VALE 2 O 3, CON 0,01 A 5,0 POR CIENTO DE UN AGENTE NUCLEANTE, CUYO TAMAÑO DE PARTICULA ES INFERIOR A 100 MICRAS; Y TRATAR LA MEZCLA CON UN AGENTE DE CUARADO EN CANTIDAD DE 0,8 A 1,2 EQUIVALENTES RESPECTO DEL NUMERO TOTAL DE EQUIVALENTES DE ISOCIANATO, A UNA TEMPERATURA COMPRENDIDA ENTRE 25GC Y 200GC. ESTOS ELASTOMEROS TIENEN APLICACIONES PARA LA FABRICACION DE ARTICULOS MOLDEADOS, CINTAS TRANSPORTADORAS Y CUBIERTAS DE NEUMATICOS.
