OXYGEN TAILORING OF POLYETHYLENE FILM RESINS

摘要

Processes are disclosed for oxygen-tailoring polyethylene resin. Polyethylen e resin is conveyed through a feed zone, a melt-mixing zone and a melt zone. T he resin is contacted with oxygen in an amount of at least 40 parts by weight O 2 per million parts by weight resin, and contacted with primary antioxidant downstream of the point or points of oxygen contact. The oxygentreated resin can be used to make polyethylene film having improved gauge uniformity.
