Abstract

Procedimiento para la obtención de copolimerizados de bloque no elastoméricos ramificados y selectivamente hidrogenados, caracterizado porque se polimeriza en varias etapas sucesivas un 60 a 95% en peso de un compuesto monovinilaromático y un 40 a 5% en peso de un dieno conjugado en un disolvente en presencia de un hidrocarburo de monolitio como iniciador agregando gradualmente los monómeros y el iniciador, y se acoplan, a continuación los copolímerizados de bloque lineales vivos.
