Abstract

Se tiene un proceso mejorado para la hidrogenación de polímeros de dieno conjugados que comprende la polimerización, de al menos un dieno conjugado con un organometal alcalino iniciador de la polimerización en un solvente adecuado creando así un polímero en crecimiento, finalizando la polimerización mediante la adición de hidrógeno y una hidrogenación selectiva efectiva en los dobles enlaces de las unidades de dieno conjugadas del polímero terminado, haciendo que el polímero se ponga en contacto, en ausencia de hidrocarburos de litio y de compuestos alcoxilitio, con hidrógeno en presencia de al menos un compuesto bis (ciclopentadienil) titanio. La mejora consiste en el uso de un benzoato de alquilo como promotor en el paso de hidrogenación. El metil benzoato es el promotor más preferido.
