Abstract:
A process for the preparation of an ethylene copolymer having a density greater than 0.900 g/cc, and a I21/I2 in the range of from 15 to 25, and a melt strength in the range of from 6 to 11 cN, the process comprising contacting ethylene and comonomer under polymerization conditions with an organometallic catalyst compound that is activated for olefin polymerization by reaction with a Lewis acid aluminum compound of the formula:RnAl(ArHal)3âˆ’n, where â€œArHalâ€  is a halogenated aryl group, n=1 or 2, and R is a monoanionic group other than a halogenated aryl group.
