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.

摘要: A laminate and a process for making it are disclosed. The laminate comprises a metal substrate and a polymer layer that adheres to at least one plasma-treated surface of the metal substrate. The polymer layer comprises a blend of a first polyolefin and a grafted polyolefin. The laminate can be prepared by plasma-treating at least one surface of a metal substrate and extruding onto the plasma-treated surface a polymer layer comprising a blend of a first polyolefin and a grafted polyolefin.
