    摘要: A method of modifying polyethylene is disclosed. The method comprises contacting the polyethylene powder with ozone. The modified polyethylene exhibits an increase in melt elasticity and the complex viscosity at low shear rates. The rheological benefits are achieved without a significant reduction in the weight average molecular weight of the polyethylene. The modified polyethylene can be used in applications that require higher melt strength such as film or blow molding.
