Control of resin split in single-reactor manufacture of bimodal polyolefins |
摘要 |
Bimodal resin products are produced in a single reactor by using two bicomponent catalyst compositions, each having a high molecular weight and a low molecular weight component, in different ratios. The HMW/LMW split of the final resin product is controlled accurately by controlling the ratio of the feed of the two bicomponent catalyst compositions. Bimodal or polymodal effects are also achieved for properties or characteristics other than molecular weight. More complex results can be achieved with more than two components. The invention is applicable to a wide variety of polymer products, particularly polyolefins and polyethylene. |
