Broad molecular weight distribution polymers with a reverse comonomer distribution and low levels of long chain branches
摘要
The present invention provides an ethylene polymer having a melt index from about 0.1 to about 100 g/10 min; a ratio of Mw/Mn from 3 to 6; a reverse comonomer distribution; less than about 0.05 long chain branches (LCB) per 1000 total carbon atoms; and less than 5% by weight of the polymer eluted below a temperature of 40°C in an ATREF test.
