Abstract
Se revela un proceso para interpolimerizar un polímero hidrocarburo aromático vinilo y un polímero de bloque. El proceso incluye los sgtes. pasos:a)el formar un precursor del polímero de bloque, de por lo menos un bloque polimérico que contiene unidades contribuidas de monómero dieno conjugado, enla presencia de un iniciador aniónico y en un diluyente inerte, teniendo el precursor del polímero de bloque, extremos vivos; b) seguidamente, el adicionaral precursor del polímero de bloque, una carga de un monómero hidrocarburo aromático vinilo y una carga adicional de un iniciador aniónico, de modo deformar simultáneamente: (1) un polímero de bloque que tiene un bloque terminal formado a partir de la carga del monómero hidrocarburo aromático vinilo fijadoal precursor del polímero de bloque, y: (2) un polímero poli (hidrocarburo aromático vinilo), interpolimerizado con el polímero de bloque. La práctica deeste proceso, permite obtener un polímero de bloque terminado en un bloque hidrocarburo aromático vinilo, tal como el SBS, interpolimerizado con unpolímero formado a partir del monómero hidrocarburo aromático vinilo, tal como el poliestireno. El interpolímero tiene una elevada resistencia al impactosegún Gardner, y goza de una buena procesabilidad.
