POLYETHYLENES WITH INCREASED MOLECULAR WEIGHT DISTRIBUTION
Methods for making olefin polymerization catalysts and methods for making polyethylene polymers using the catalysts are provided. The polyethylenes can have a molecular weight distribution (MWD) of about 4.5 to about 14, a slope of strain hardening greater than about 0.75, and a melt flow ratio (MFR...

Summary: | Methods for making olefin polymerization catalysts and methods for making polyethylene polymers using the catalysts are provided. The polyethylenes can have a molecular weight distribution (MWD) of about 4.5 to about 14, a slope of strain hardening greater than about 0.75, and a melt flow ratio (MFR) greater than or equal to 8.33+(4.17×MWD). |
