Abstract

Se describe un procedimiento de etapas multiples para la polimerizacion de olefinas CH2=CHR, en donde R es hidrogeno o un radical alquilo, cicloalquilo o arilo con 1-10 átomos de carbono, que comprende dos etapas de polimerizacion; en una primera etapa, en presencia de un catalizador de titanio o vanadio y trabajando en uno o más reactores, se prepara un polímero olefínico con valores particulares de porosidad; en una segunda etapa, en presencia de dicho polímero poroso y un compuesto de metaloceno y/o sus productos de reaccion, una o más olefinas, que son iguales a o diferentes de aquellas polimerizadas en la primera etapa, se polimerizan en uno o más reactores.
