| titleOfInvention | Catalyst composition and process for polymerizing polymers having multimodal molecular weight distribution |
| abstract | There is disclosed a supported olefin polymerization catalyst composition comprising a precursor and a catalyst activator. The precursor comprises a magnesium compound e.g., dibutylmagnesium, a cyclopentadienyl group - containing zirconium compound, and a titanic and/or a vanadium compound e.g., TiCl4, and an organic compound, e.g., an alcohol. The catalyst activator is a mixture of a conventional Ziegler/Natta co-catalyst and a zirconium sites activator, e.g., methylaluminumoxane. The catalyst is used in the preserve of small amounts of hydrogen to produce polymers having multimodal molecular weight distribution in a single reactor. |
