Improved process to produce long-chain branched polyolefins using dienes |
abstract |
The present disclosure provides methods for producing an olefin polymer including: i) contacting alpha-olefin with a first catalyst system comprising a first non-metallocene catalyst, a first activator, and a reversible chain transfer agent to form a first polymer; ii) contacting the first polymer with a coupling agent in the presence of a catalyst, an activator; and iii) obtaining a second polymer. The present disclosure further provides polymers having a g'vis value from about 0.4 to about 0.8 and a vinyl unsaturation content of 0.8 or greater vinyls/1000 carbons, and preferably low gel content. |
