1. Use water purification catalyst to control the hydrogen content and molecular weight of particles in the polymerization reactor.

摘要

The present Invention provides a dual Catalyst Systems containing metallocene Catalyst and a catalyst for purification of hydrogen, and polymerization processes employing these dual Catalyst Systems.Due to a reduction in the levels of hydrogen in the process of polymerization, olefin Polymers produced from the polymerization processes may have a higher Molecular Weight, a lower rate of fusion, and higher levels of unsaturation.
