Abstract

Procedimiento para la obtención de un copolímero elástico distribuido de manera sustancialmente aleatoria que comprende copolimerizar por lo menos un dieno conjugado con por lo menos un compuesto monovinilaromático sustituido bajo condiciones de temperatura y presión de polimerización en solución, en presencia de un iniciador organolitio y por lo menos un agente de distribución aleatoria, llevándose a cabo dicho procedimiento de forma sustancialmente continua en una serie de por lo menos dos reactores en los cuales dicho dieno conjugado, dicho compuesto monovinilaromático, dicho iniciador organolitio, dicho agente de distribución aleatoria, y cualquier diluyente se suministran al primer reactor de dicha serie de reactores, y dicho copolímero de distribución al azar se extrae como producto del último reactor, caracterizado porque a dicho primer reactor se suministra por lo menos un agente de tratamiento de alcoxisilicio en una cantidad eficaz para aumentar sustancialmente la elaborabilidad de dicho copolímero de distribución al azar.
