| 摘要 |
<p>The invention provides a water degradable polyolefin-containing film having greater than about 55 weight percent of a modified polyolefin and less than about 45 weight percent of unmodified poly(ethylene oxide). The polyolefin is modified by grafting thereto a monomer selected from 2-hydroxyethyl methacrylate and polyethylene glycol ethyl ether methacrylate in an amount ranging between about 0.1 weight percent and about 30 weight percent, based on the total weight of the polymer blend. The polyolefin-containing film, 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 polyolefin-containing film of the invention.</p> |
