Abstract
A thermoplastic film comprises a polyolefin, such as polyethylene, as a major constituent, poly(ethylene oxide) as a minor constituent and has a total of from about 0.1 weight percent to about 30 weight percent of monomer grafted to the polyolefin and the poly(ethylene oxide). The film exhibits an inverse phase morphology so that the poly(ethylene oxide) forms a continuous phase and the polyolefin forms a dispersed or discontinuous phase in the film. Desirably, the film can be used in disposable personal hygiene articles.
