    Abstract: Water-absorbent sheet material is manufactured by contacting a liquid-sorbent polymerization initiating substrate with polymerization catalyst and/or polymerization initiator, embedding the polymerization initiating sheet material with clay-containing slurry, and heating the embedded sheet material to polymerize the monomer and vaporize, to form a water sorbent polymer and to interlock the polymer and clay in the sheet material. Manufacture of water-absorbent sheet material comprises contacting a liquid-sorbent polymerization initiating substrate with a polymerization catalyst and/or a polymerization initiator to form a polymerization-initiating sheet material for a subsequently embedded monomer; embedding the polymerization initiating sheet material with a clay-containing slurry comprising water, clay, and polymerizable monomer to form a water-sorbent polymer; and heating the embedded sheet material to polymerize the monomer and vaporize at least a portion of the slurry water to form a water sorbent polymer and to interlock the polymer and clay in the sheet material. The slurry comprises less than 50% water. The weight ratio of monomer to clay is 1:19, throughout a portion of the thickness of the polymerization-initiating sheet material for intimate contact with the polymerization catalyst or polymerization initiator to initiate polymerization of the monomer.

    Abstract: A waterproofing article in the form of rod-, or rope-shaped clay-containing compositions, and a method of waterproofing using the article, whereby a water-penetrable, degradable, or water-soluble film or coating forms an outer surface of the article for avoiding premature hydration of an underlying clay-containing composition. In the preferred embodiment, an inner core of a water-swellable clay-containing composition includes a coating of a water-removable or degradable material, completely encasing the major outer surfaces of the composition, having controlled, predetermined water-penetration; high pH degradability; or water-solubility so that the core of water-swellable clay-containing composition is quickly hydrated after water-penetration of the coating material, and to prevent clay hydration during installation, prior to water-penetration of the coating material.

    Abstract: A polymer-containing sheet material is manufactured by embedding a polymerization solution, containing a polymerizable monomer throughout at least a portion of the thickness of a polymerization-initiating sheet material, for intimate contact with the polymerization catalyst or polymerization initiator (20) to initiate polymerization of the monomer. Manufacture of a polymer-containing sheet material comprises contacting a liquid-sorbent sheet material, or material used to make the liquid-sorbent sheet material, with a polymerization initiator or polymerization catalyst in an amount to initiate polymerization of a later added polymerizable monomer, to produce a polymerization-initiating sheet material; embedding a polymerization solution, containing a polymerizable monomer throughout at least a portion of the thickness of the polymerization-initiating sheet material, for intimate contact with the polymerization catalyst or polymerization initiator to initiate polymerization of the monomer; and subjecting the sheet material to conditions to polymerize the monomer, to form a polymer embedded in the sheet material, thus securing the polymer to the sheet material.
