Patent number: 6590025Abstract: Disclosed are modified latexes having improved drying speed, comprising a polymer having one or more pendant side chains, such side chain comprising the product of the reaction between a mono- or poly-functional group capable of reacting with an acid or hydroxyl unit, and such units present on the precursor polymer. Such modified latexes are storage-stable one-pack compositions useful alone or in combination in coating applications, or as adhesives, sizing agents, composites, impregnants, castings, caulks, and non-woven binders. Also disclosed is a method for providing a crosslinked protective coating on a substrate, comprising the steps of: applying a coating of the composition of the present invention to the substrate; and allowing the composition to cure at ambient temperature or greater, or applying radiation to the composition to effect curing.Type: GrantFiled: February 13, 1997Date of Patent: July 8, 2003Assignee: Rohm and Haas CompanyInventors: Virginia Ann Carlson, Ronald Scott Beckley

Patent number: 6565981Abstract: A composite of a substrate having an application of superabsorbent polymer. The composite is made by applying, directly onto the substrate, an application of a polymer that will, upon being subjected to radiation, convert to a superabsorbent polymer. The substrate with applied polymer is subjected to radiation, such as being heated at a sufficient temperature for a sufficient time, to obtain the composite of substrate with superabsorbent polymer adhered to it.Type: GrantFiled: March 30, 1999Date of Patent: May 20, 2003Assignee: Stockhausen GmbH & Co. KGInventors: Bernfried Messner, Whei-Neen Hsu, Robert Agne
