ABSTRACT:
The invention provides a water degradable modified polyolefin-modified poly(ethylene oxide-containing film having greater than about 55 weight percent of a modified polyolefin and less than about 45 weight percent of a modified poly(ethylene oxide). The polyolefin and poly(ethylene oxide) polymers are modified by having grafted thereto from about 0.1 weight percent to about 30 weight percent of a monomer selected from 2-hydroxyethyl methacrylate or polyethylene glycol ethyl ether methacrylate. The modified polyolefin-modified poly(etheylene oxide)-containing film of the invention, when immersed in water for about 30 seconds, loses at least 10% in two or more of the tensile properties: percent strain-to-break, peak stress, energy-to-break and modulus when compared to the dry or pre-immersion values. Also provided are flushable personal care articles such as infant diapers, feminine hygiene napkins, and adult incontinence garments having a backing or barrier layer comprising a water degradable modified polyolefin-modified poly(ethylene oxide)-containing film of the invention.
