Abstract
A method of modifying a polyethylene material is accomplished by providing a polyethylene resin. The initial rheological breadth of the polyethylene resin is determined. The resin is then modified to adjust the rheological breadth of the polyethylene from the initial rheological breadth to a different rheological breadth that corresponds to a desired resin property, such as haze. A method for predicting clarity and rheological breadth properties is also provided, which utilizes a template of measured properties for polyethylene resins.
