Abstract

La presente invencion se refiere a un procedimiento continuo para la obtencion de elastomeros a base de dienos conjugados o a base de dienos conjugados y de compuestos vinilaromaticos a base de alquenos, llevandose a cabo la polimerizacion con respeto de determinados tiempo de residencia de los monomeros empleados y de los elastomeros obtenidos en los reactores y con respeto de un determinado gradiente de temperatura en el primer reactor. Los elastomeros, obtenidos segun el procedimiento de la invencion se caracterizan, especialmente, por un bajo contenido en iones metalicos, un bajo contenido en cenizas y un elevado contenido en enlaces cis-1,4 en el polimero. Ademas el procedimiento segun la invencion se presenta como especialmente economico.
