Processes for transitioning between chrome-based and mixed polymerization catalysts |
| abstract |
The present invention provides a processes for transitioning among polymerization catalyst systems, preferably catalyst systems, which are incompatible with each other. Particularly, processes for transitioning among olefin polymerization reactions utilizing silyl-chromate catalyst systems and metallocene catalyst systems. |
