ZIEGLER-NATTA CATALYST COMPOSITIONS TO PRODUCE POLYETHYLENE WITH A HIGH MOLECULAR WEIGHT TAIL AND METHODS TO DO THE SAME. |
| abstract |
Methods for preparing a polymerization catalyst component are provided, in which a magnesium component, a Lewis acid solubilizing component, a titanium compound, optionally a transition metal compound different from the titanium compound, and usually a Inert fillers are combined in a paste agent and spray dried to produce a catalyst precursor in the form of a particle of porous solid and substantially spherical. The methods and catalysts of this description can provide homopolymer and copolymer resins of ethylene having a high molecular weight glue and a widened molecular weight distribution as compared to the more traditional Ziegler-Natta catalysts. |
