Chromium-based polymerization catalyst, preparation method thereof and polymer produced using the same |
| abstract |
Catalyst systems for polymerizing olefins include a catalyst comprising chromium and a promoter comprising a substituted or unsubstituted non-transition metal cyclopentadienyl (Cp) compound. The catalyst also includes an inorganic oxide support. The method for preparing the catalyst includes contacting the support with chromium and the non-transition metal Cp compound. The support may be contacted with a solution comprising the non-transition metal Cp compound prior to entering the reaction zone. Processes for the polymerization of at least one olefin include contacting a catalyst comprising chromium and a promoter comprising a non-transition metal Cp. The polymerization can be carried out in the presence of hydrogen. Using cocatalysts with catalysts increases some of the properties of the polymers produced by the process. The polymer composition produced by this method has a variety of unique properties, including PDI greater than 30. |
