Abstract
A process for polymerizing an olefin is disclosed. The olefin is polymerized with a catalyst precursor in the presence of an activator and an organosilane modifier. Use of the organosilane increases polyolefin molecular weight. The process is easy to practice and affords polyolefins with conventional polymerization methods such as slurry polymerizations or gas-phase polymerizations.
