Claims
- 1. A process for producing linear polyethylene containing a terminal fragment having long chain branches, said process comprising polymerizing ethylene in the presence of a catalyst comprising:
- (a) a Group 4B to 8 transition metal compound,
- (b) an organoaluminum compound of the general formula R.sub.1 R.sub.2 AlR.sub.p wherein R.sub.1 and R.sub.2 are the same or different hydrocarbyl groups having from 1 to 18 carbon atoms and R.sub.p is a polymeric hydrocarbyl group having a number average molecular weight in the range of about 1000 to about 100,000 and a long chain branching frequency of about 0.005 to about 0.0005 per unit molecular weight, and
- (c) an aluminum alkyl cocatalyst.
- 2. The process in accordance with claim 1 wherein R.sub.p has a number average molecular weight of about 1000 to about 20,000.
