Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLIMEROS BIMODALES O MULTIMODALES DE DIENOS CONJUGADOS Y DE COPOLIMEROS BIMODALES O MULTIMODALES DE DIENOS CONJUGADOS ENTRE SI O CON COMPUESTOS VINILAROMATICOS. CONSISTE EN LA REACCION DE LOS MONOMEROS ELEGISO, A UNA TEMPERATURA ENTRE 20 Y 200 C, EN PRESENCIA DE UNA COMPOSICION CATALITICA CONSTITUIDA POR UN INICIADOR DE ORGANO-LITIO, UN COMPUESTO DE METAL ALCALINOTERRO Y UN COMPUESTO ORGANOMETALICO DE UN METAL DE LOS GRUPOS 2B O 3A DE LA TABLA PERIODICA. LA REACCION SE LLEVA A CABO EN CONTINUO, EN UN DISOLVENTE HIDROCRBONADO, HACIENDO PARAR HIDROGENO A TRAVES DEL MEDIO DE REACCION DURANTE LA POLIMERIZACION.
