NOVEL CATALYST COMPOSITIONS AND METHOD OF MAKING AND USING THE SAME FOR THE POLYMERIZSATION OF OLEFIN. HIGH DENSITY POLYETHYLENE

摘要

An ethylene polymer having (i) a density defined by equation (1) ? > a - b Log M (1) where ? is a density of the polymer in g/cc, log M is a log weight average molecular weight of the polymer, a is about 1.0407, and b is about 0.0145; and (ii) a polydispersity index of greater than about 5.
