Abstract
An aqueous solution of (a) acrylic acid; (b) an iron acrylate from the group consisting of ferrous or ferric acrylates; (c) methylene bis acrylamide; and (d) a water-soluble polymerization catalyst which also is a reducing agent when the iron acrylate is ferric acrylate and an oxidizing agent when the iron acrylate is ferrous acrylate; with the ratio of (a) to (b) being between 10:0.1 to 10:1.5, which solution forms a water resistant gel.
