Abstract
Processes are disclosed for oxygen-tailoring polyethylene blow molding resin. Polyethylene resin is conveyed through a feed zone, a melt-mixing zone and a melt zone, wherein the temperature of the polyethylene resin is from about 216° C. to about 260° C. in the melt zone. The resin is contacted with oxygen in an amount of at least about 20 parts by weight oxygen per million parts by weight resin. The oxygen-treated resin can be used to make polyethylene blow molded articles having improved melt strength, processability, and die swell.
