Abstract

La presente invención se refiere a procesos para la preparación de un copolímero de bloque que comprende al menos un bloque polimérico de un monómero polimerizable aniónicamente, seleccionado del grupo que consiste de hidrocarburos aromáticos de monovinilo, dienos conjugados y mezclas de los mismos, y un bloque polimérico de polidimetilsiloxano, el proceso comprende los pasos de: (a) polimerizar el(los) monómero(s) polimerizable(s) aniónicamente en la presencia de un iniciador de metal organoalcalino, en un solvente de hidrocarburos hasta que se completa en forma sustancial; (b) hacer reaccionar las cadenas de polímero activo así obtenido, con un agente de cruzamiento o ligazón, seleccionado del grupo que consiste de siloxanos de anillo deformado o estirado, aldehídos, cetonas, óxidos de alquileno y epóxidos; (c) hacer reaccionar el producto del paso (b) con hexametilenclotrisiloxano, en la presencia de un promotor polar; y (d) hacer terminar la polimerización.
