Abstract

Procedimiento para la preparación acoplada de un polímero orgánico activado por metal alcalino, cuyo polímero orgánico es de fórmula Q-M en la que Q es un polímero hidrocarbonado que tiene un átomo de metal alcalino M terminalmente unido a él, caracterizado dicho procedimiento por las siguientes fases: (a) En un primer paso de acoplamiento, la reacción de dicho polímero activado Q-M con un primera sustancia de acoplamiento no terminante, de tal modo que se forme un polímero orgánico inicial acoplado de fórmula Qm''-X-Mn donde Q representa una de m¿cadenas poliméricas Q acoplada a través de la unidad de acoplamiento X que se deriva de dicha primera sustancia acoplante no terminante y m'' y m son enteros esencialmente iguales uno a otro. (B) En un segundo paso de acoplamiento, se acopla de nuevo dicho polímero orgánico acoplado Qm''-X-Mn con una segunda sustancia de acoplamiento para formar un polímero nuevamente acoplado.
