Abstract

The present invention discloses filled polymer compositions having a unique porous microstructure and enhanced breathability. In one embodiment, the composition of the present invention is flushable and comprises a water-responsive polymer of ethylene oxide and unmodified clay or layered silicate composite. The compositions of present invention are useful for manufacturing breathable and flushable films, fibers and articles. Advantageously, breathable films, fibers and articles of the present invention can be formed economically and efficiently without foaming or stretching.
