Abstract: Nonwoven fabrics characterized by a superior balance of strength and softness are formed utilizing an aqueous emulsion prepared by the emulsion polymerization of: 30 to 50% by weight of vinyl ester of an alkanoic acid; 10 to 30% by weight ethylene; 30 to 50% by weight of C.sub.4 -C.sub.8 alkyl acrylate; and 1 to 5% by weight of copolymerizable N-methylol containing monomer; wherein the polymerization is performed using batch or semi-batch techniques.

Abstract: A dry, solid, water-swellable, water-insoluble absorbent composition of matter comprises an ionic complex of a water-soluble anionic poly-electrolyte and a polyvalent metal cation. The composition is characterized by an ability to uncomplex at an elevated pH and recomplex at a lower pH.

Abstract: The aqueous dispersibility of a water-absorbent composition of matter is improved by a surface treatment which ionically complexes the surface thereof to a moderate degree. A dispersion is formed comprising a water-absorbent composition of matter based on an anionic poly-electrolyte, at least one polyvalent metal cation, and a dispersing medium in which the composition of matter is substantially insoluble. The dispersion is maintained within a given temperature range for a period of time sufficient to ionically complex the exposed surface of the composition of matter, and the dispersing medium is then removed. The product is characterized by a linkage density which is greater at the surface thereof than in the interior thereof and by the presence of ionic linkages at the surface thereof.
