Abstract:
The present invention describes a metallocene catalyst based on a transition metal of group 4 or 5 of the periodic table; supported on a hybrid catalytic support with aliphatic organic groups and a process for supporting metallocene on the hybrid catalytic support. The supported metallocene catalyst provides an ethylene polymer with broad or bimodal molecular weight distribution in the presence of only one metallocene complex on the support.
