Abstract
Polímeros acoplados y proceso para su preparación. Comprende reaccionar un polímero vivo terminado en metal alcalino con un agente de acoplamiento de fórmula (I) en donde R{sub,1}, R{sub,2} y R{sub,3} tienen los significados dados en la descripción. Por medio de este agente de acoplamiento particular, la eficacia de acoplamiento es relativamente alta y no se generarán materiales perjudiciales que puedan corroer las tuberías. El polímero acoplado obtenido tiene un indice de acoplamiento menor de 3 y buenas propiedades físicas cauchutosas, transparencia y resistencia al desgaste.
