Simplified polyethylene catalyst system |
| abstract |
Vanadium catalyst with improved support, in particular catalytic system of Beran et al. improved and an ethylenic polymerization process in which the improvement results from the attachment of the promoter to a component of the catalytic composition, so that it constitutes a molecular structural component of the catalyst and that it is not added separately to the reaction polymerization, but instead it is part of the catalytic composition added to the reaction. |
