ABSTRACT:
Generally, linear polyethylene containing long chain branching is obtained by polymerizing ethylene in the presence of a catalyst comprising a transition metal compound such as titanium chloride, an organoaluminum compound represented by the formula R.sub.1 R.sub.2 AlR.sub.p wherein R.sub.1 & 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 containing long chain branching and an aluminum alkyl cocatalyst.
