摘要:
Ethylene polymerization processes and polymers formed from the same are discussed herein. The ethylene polymerization processes generally include introducing ethylene monomer into a polymerization reaction zone; introducing a chromium oxide based catalyst into the polymerization reaction zone; introducing a quantity of hydrogen into the polymerization reaction zone; and contacting the ethylene monomer with the chromium oxide based catalyst in the polymerization reaction zone in the presence of hydrogen to form polyethylene, wherein the polyethylene formed in the presence of hydrogen exhibits an MI2 that increases with an increasing quantity of hydrogen and a molecular weight and molecular weight distribution that remains essentially constant with an increasing quantity of hydrogen.
