Abstract

The present invention is directed to water-dispersible polymers. The present invention is also directed to a method of making water-dispersible polymers and their applicability as binder compositions. The present invention is further directed to fiber-containing fabrics and webs comprising water-dispersible binder compositions and their applicability in water-dispersible personal care products.

Claims

1. A composition comprising:

approximately 50% to 95% by weight sodium polyacrylate; and

approximately 5% to 50% by weight of a styrene emulsion.

2. The composition of claim 1, wherein the styrene emulsion is selected from styrene acrylic or styrene-butadiene emulsion.

3. The composition of claim 1, wherein the composition comprises approximately 83% by weight sodium polyacrylate and approximately 17% by weight styrene emulsion.

4. The composition of claim 1, wherein said composition is sprayable.
