Polymerization process for improved reactor performance of metallocenes |
摘要 |
The present invention relates to a process for polymerizing olefin(s) in the presence of metallocene-type catalyst compound, an activator and an inorganic oxide support, a Group 13 containing compound and a carboxylic acid, where the carboxylic acid is added to the polymerization reactor separately. The invention also relates to a process for transitioning from one polymerization catalyst to another.
