Abstract
A thermoplastic composition that includes an unreacted mixture of a polyethylene oxide polymer, a polyolefin polymer, an aliphatic polyester polymer, and, optionally, a compatibilizer for the polymers. One embodiment of such a thermoplastic composition is a mixture of polyethylene oxide polymer, poly(lactic acid) polymer, and polyethylene polymer. The thermoplastic composition is capable of being extruded into fibers that may be formed into nonwoven structures that may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
