Abstract
Processes are disclosed for oxygen-tailoring polyethylene resin. Polyethylene resin is conveyed through a feed zone, a melt-mixing zone and a melt zone. The resin is contacted with oxygen in an amount of at least 40 parts by weight Oper million parts by weight resin, and contacted with primary antioxidant downstream of the point or points of oxygen contact. The oxygen-treated resin can be used to make polyethylene film having improved gauge uniformity.
