PREPARATION OF POLYETHYLENE |
摘要 |
A polyethylene having improved rheological properties is disclosed. The polyethylene has a melt index (MI2) from about 0.01 dg/min to about 50 dg/min and a melt strength ( eta ) that satisfies MI2 x eta >/= 3.5. A process for making the polyethylene is also disclosed. The process uses an azaborolinyl-containing single-site catalyst in the presence of hydrogen, where the hydrogen consumption is controlled to be less than 30%.
