Abstract
A water-responsive, thermoplastic article is formed from a composition of matter comprising a blend of polyolefins and poly(ethylene oxide). A water-dispersible article can be made from a blend having from about 1 weight percent to about 35 weight percent polyolefin and from about 99 weight percent to about 65 weight percent of poly(ethylene oxide). The water responsiveness of the article can be varied by modifying the polyolefin and increasing the content of polyolefin in the blend upwards to about 55 weight percent. The compositional blends can be made into a flushable barrier film for use in a disposable absorbent article, such as a diaper or feminine pad, or can be used to make a water responsive tampon tube. A method of making the article comprises blending together the polyolefin and poly(ethylene oxide) under melt conditions and forming the article.
