CATALYST COMPONENTS FOR THE POLYMERIZATION OF DIENES, CATALYST OBTAINED THEREFROM, AND PROCESS FOR THE PREPARATION OF POLYDIENES USING THE SAME

摘要

The present invention relates to a catalyst component comprising a compound of a metal selected from the group consisting of Co, Ni and rare earth elements supported on a polymer having a porosity (mercury) higher than 0.02 cm3/g. The use of the above catalyst component makes it possible to prepare dienic polymers, in gas-phase with high yields.
