Abstract:
1. A method of preparing a polyethylene composition comprising a low-molecular-weight (LMW) ethylene homopolymer component and a high-molecular-weight (HMW) ethylene interpolymer component, said method comprising: polymerizing the low-molecular weight ethylene component in one reactor, and polymerizing the high-molecular weight ethylene component in a different reactor, and wherein the two reactors are operated in series or operated in parallel, and wherein the LMW component has a molecular weight distribution, MWD wherein the HMW component has the following properties: a molecular weight distribution, MWD wherein the HMW component has a weight average molecular weight, Mw, from about 100,000 to about 600,000 g/mole.
