Abstract: Metal ion crosslinked superabsorbent polymers and a process for making them are described wherein high concentrations of polyhydroxylated materials are incorporated in order to reduce the sensitivity of the superabsorbent composition to solutions containing dissolved salts. Also provided is a process for forming crosslinked superabsorbents containing high solids polymer content.

Abstract: A fibrous web having an enhanced capacity for water absorption is produced by impregnating an absorbent fabric with a polymer or copolymer capable of forming by cross-linking an absorbent polymer or copolymer and subsequently heating the treated fabric effecting cross-linking of the polymer to form an absorbent polymer. The product may comprise a non-woven fibrous web or mat having a water-insoluble binder on one surface and a cross-linked hydrophilic polymer or copolymer on its opposite surface.

Abstract: A method for forming a fabric web by wet-laying fibers on paper-making equipment, the web comprising staple length natural or synthetic fibers and optionally wood cellulose papermaking fibers and an adsorbed polymeric surface active agent. The method comprises making up an aqueous fiber furnish with a polymeric surfactant having a plurality of both hydrophilic and hydrophobic groupings per molecule. The polymeric surfactant is adsorbed by the fibers and may be added to the fibers or it may be included in the aqueous carrier medium. In either case, the finished web contains and is improved by the inclusion of the polymeric surfactant.

Abstract: Superabsorbent synthetic fibers are prepared by a method wherein segments of synthetic fibers are coated with a solution of (a) a hydrophilic, uncomplexed polymer and (b) a complexing agent, and the coated fibers are fluff or flash dried causing the polymer to complex and to form a superabsorbent coating on the synthetic fibers in situ.

Abstract: Process for chemically modifying microwave interactive film and chemically modified microwave interactive film, chemically modified microwave interactive laminates and packages containing chemically modified microwave interactive film.

Abstract: A method for forming a fibrous web by wet-laying fibers on paper-making equipment, the web comprising staple length natural or synthetic fibers and wood cellulose paper-making fibers wherein a water furnish of the fibers is made up with an associative thickener in the absence of a conventional surfactant. A preferred associative thickener for use with hydrophobic fibers is a urethane block copolymer having a polyethylene glycol backbone, the associative thickener acting as both surfactant and thickener. With predominately cellulosic fibers, i.e. conventional wood cellulose fibers, or a mixture of conventional and contorted wood fibers, and synthetic cellulosic fibers, such as rayon, a hydroxyethyl cellulose having a long alkyl side chain is preferred. Excellent consistency of the water and fiber dispersion is obtained at relatively low viscosity with rapid drainage of water from the wire and uniform formation of the web.

Abstract: A coated ink jet printing substrate where said coating utilizes an insolubilized hydrophilic polymer.

Abstract: Admixture compositions for hydraulic cement compositions are disclosed which comprise a borate ester of a polyhydroxy compound. The admixtures are effective water-reducing agents at relatively low dosages in hydraulic cements. They generally provide water reduction levels equal to or greater than those provided by the corresponding non-esterified polyhydroxy compound with a lesser degree of set retardation.
