Abstract:
A multiple zone process which comprises:(a) polymerizing an olefin in a first reaction zone with a single-site catalyst in the presence of a non-alumoxane activator at a temperature within the range of about 130.degree. C. to about 200.degree. C. to produce a first polymer having a weight average molecular weight (Mw) within the range of about 5,000 to about 500,000; and(b) transferring the first polymer to a second reaction zone at a higher temperature within the range of about 140.degree. C. to about 280.degree. C. with additional olefin in the presence of a Ziegler-Natta catalyst to produce a final polymer composition having a density less than about 0.98 g/mL and Ml.sub.2 within the range of about 0.5 to about 300 dg/min.
