Abstract
PROCEDIMIENTO PARA LA OBTENCION DE COPOLIMEROS TERMOELASTOMERICOS DE TRES BLOQUES, DE LOS TIPOS ABA Y ABC, EN LOS CUALES LOS BLOQUES A Y C SON DE NATURALEZA PLASTOMERICA Y EL B ELASTOMERICO. CONSISTE EN LA POLIMERIZACION SUCESIVA DE LOS MONOMEROS CORRESPONDIENTES AL PRIMER BLOQUE PLASTOMERICO, AL BLOQUE ELASTOMERICO Y AL SEGUNDO BLOQUE PLASTOMERICO, EN ESTE ORDEN, EN PRESENCIA DE UN SISTEMA CATALITICO, CONSTITUIDO POR UN COMPUESTO DE ALUMINIO DE FORMULA AIR2X'', EN LA QUE AMBOS R PUEDEN SER HIDROGENO O RADICALES ALQUILICOS C1-8; Y X'' ES UN HALOGENO O UN REDICAL C1-8; UN HALOGENO; UN DIHALOGENO; Y UN DERIVADO HALOGENADO. LA REACCION SE LLEVA A CABO EN UN DISOLVENTE ORGANICO QUE PUEDE SER UN HIDROCARBURO ALIFATICO, UN DERIVADO HALOGENADO DE ESTE O SUS MEZCLAS, A UNA TEMPERATURA ENTRE -20 GRADOS C Y 100 GRADOS C. ESTOS COMPUESTOS TIENEN APLICACIONES PARA LA FABRICACION DE MATERIALES RESISTENTES A LA OXIDACION O AL ENVEJECIMIENTO.
