Abstract
A water soluble polymer comprising from about 25 weight % to about 90 weight % of an unsaturated carboxylic acid/unsaturated carboxylic acid ester terpolymer; from about 10 weight % to about 75 weight % of a divalent ion inhibitor and from about 0 weight % to about 10 weight % of a plasticizer is soluble in an aqueous environment having a divalent ion concentration less than about 50 ppm and a monovalent ion concentration of less than about 0.5 weight %. Also disclosed is a water dispersible fibrous fabric having a fibrous substrate and an effective amount of the binder distributed on the substrate and a method of making a water dispersible fibrous fabric.
