Abstract:
This invention relates to a process to polymerize olefins by contacting one or more olefins with a catalyst system comprising an organoaluminum treated layered silicate support, and a bridged metallocene compound and obtaining a polyolefin having a g′vis of 0.90 or more and an MIR of 30 or less.
