Abstract
An improved process for polymerizing olefins in the presence of a catalyst employing hydrogen for molecular weight control is disclosed wherein the improvement resides in adding additional hydrogen to the polymer slurry produced in the reactor system so as to eliminate or reduce the formation of gels in articles fabricated from the resultant polymer.
