Supported chromium polymerization catalyst and process using the same |
| abstract |
This invention relates to a process of polymerizing ethylene in a reactor comprising contacting a catalyst system comprising a supported chromium catalyst and an aluminum alkyl cocatalyst, where the catalyst and cocatalyst are contacted by cofeeding the catalyst and cocatalyst to the reactor or feeding the catalyst and cocatalyst separately to the reactor, where the catalyst and cocatalyst are not contacted prior to the step of feeding or cofeeding, with ethylene, and from 0 to 50 mole % of one or more comonomers, where the polymerization occurs at a temperature between 50 and 120°C, and the molar ratio of aluminum from the cocatalyst to the chromium in the supported chromium catalyst is 30:1 or more. |
