Abstract

La invencion se refiere a la hidrogenacion selectiva de polímeros no saturados, especialmente polímeros elastoméricos que contienen anillos aromáticos y enlaces dobles carbono-carbono, por ejemplo, polímeros preparados a partir de estireno y butadieno. En este caso, la molécula del polímero contiene enlaces dobles internos y de grupo terminal, así como enlaces no saturados en anillos aromáticos. De conformidad con la invencion, solamente los enlaces internos y terminales no saturados se hidrogenan, por lo que las propiedades de resistencia térmica y a la intemperie del producto se incrementan. Convencionalmente, la hidrogenacion se ha realizado por medio de catalizadores de níquel o cobalto, pero ahora se ha observado que un complejo catalizador de metaloceno/alumoxano no solamente cataliza la reaccion de polimerizacion de varios compuestos olefínicos sino que cataliza también la hidrogenacion selectiva de polímeros no saturados, de preferencia polímeros de bloque estireno-butadieno-estireno.
