Abstract
The present invention relates a process for the preparation of catalytic support and the supported metallocene catalysts used in the production of ethylene homopolymers and ethylene copolymers with α-olefins, of high and ultra high molecular weight with broad molecular weight distribution, in gas or liquid phase polymerization processes, the latter being in slurry, bulk or suspension, and the products obtained from these processes.
