Inverse phase compositions comprising a polyolefin, such as polyethylene, and poly(ethylene oxide) and methods of making inverse phase compositions are described. The inverse phase compositions exhibit an inverse phase in which the volume minority constituent, the poly(ethylene oxide), forms a continuous phase and volume majority constituent, the polyolefin, forms a dispersed or discontinuous phase in the continuous poly(ethylene oxide) phase. The inverse phase compositions have beneficial water degradable properties and can be used in the manufacture of disposable personal hygiene articles. In at least one desirable embodiment, the polyolefin and the poly(ethylene oxide) are grafted with a polar, vinyl monomer in a reactive extrusion process. |
