Patent number: 9493669Abstract: Provided are methods for using compositions of matter which exist in a powdered, free-flowing form to which water is added preferable just prior to the time of use, to yield flowable liquid compositions which are spreadable, dispersible or sprayable onto various substrates. In some embodiments the free-flowing compositions contain water-soluble styrene/acrylic acid copolymers, and can surprisingly comprise relatively large amounts of water on the order of about 20% or more, while remaining in the form of a free-flowing powder prior to their combination with additional water to yield the spreadable, dispersible or sprayable liquid compositions. By the present disclosure, shelf life concerns are eliminated, as the compositions provided have an essentially indefinite shelf life, and transportation and handling ease are greatly increased over prior art compositions due to less weight by the absence of large relative quantities of water present in prior art compositions.Type: GrantFiled: January 26, 2015Date of Patent: November 15, 2016Assignee: CITADEL RESTORATION AND REPAIR, INC.Inventor: Patrick Ilfrey

Publication number: 20020161107Abstract: Forming graft copolymers in water using labeling of water soluble polymers with photoinitiators. The water soluble polymers can form environmentally responsive hydrophobically stimulated cages, which respond to pH, salt concentration, and/or the addition of water miscible solvents to the aqueous solutions. When the cage is “closed,” irradiation leads to radicals that cannot escape from the cage and therefore don't cause substantial polymerization of water soluble monomers in the same solution. When the cage is open via change of pH, salt concentration and/or solvent composition, the photochemically produced free radicals become exposed and cause polymerization. Under certain conditions, only graft copolymers will be formed. These graft copolymers can form a physical hydrogel in which the crosslinks are reversible. Consequently, the gel and sol states are likewise reversible.Type: ApplicationFiled: February 22, 2001Publication date: October 31, 2002Applicant: Polytechnic UniversityInventors: Mark M.

Patent number: 6323306Abstract: High molecular weight, water-soluble, cross-linked cationic polymers are prepared by reacting amine-functionalized cationic base polymers, in which the monomer units of the base polymer contain from about 0.05 to about 5.0% amine functionalized monomer units and from about 95 to about 99.95% additional monomer units, including cationic monomer units and optional non-cationic monomer units, with an amount of a cross-linking agent, reactive with the amines of the base polymer, providing between about 0.02 to about 3.0 equivalents of cross-linking agent reactive groups per each mole of amine. The polymers are useful as coagulants and as coatings.Type: GrantFiled: September 8, 1998Date of Patent: November 27, 2001Assignee: Ciba Specialty Chemicals Water Treatments Ltd.Inventors: Zhiqiang Song, George W.

Publication number: 20010023274Abstract: Methods and apparati have been developed for producing a suspension of predominately amorphous polymer particles, wherein the method includes thermally treating a suspension that includes crystalline or semi-crystalline polymer particles. The thermal treatment includes (a) heating a suspension of polymer particles of an appropriate size to a temperature effective to cause the polymer to become amorphous, and then (b) cooling the suspension of amorphous polymer particles below the melting point of the polymer at a rate effective to prevent substantial coalescence of the polymer particles. The method and apparati are effective for use with a variety of polymers having suitable crystallization parameters, although polyhydroxyalkanoate (PHA) polymers are preferred, particularly in an aqueous suspension medium. For PHA polymers, the polymer particles subjected to treatment preferably are of a size of less than 5 &mgr;m, or more preferably less than 1.5 &mgr;m in diameter.Type: ApplicationFiled: April 26, 2001Publication date: September 20, 2001Applicant: Metabolix, Inc.Inventors: Daniel Horowitz, Tillman U.

Patent number: 6291554Abstract: Disclosed is an anionic, self-emulsified aqueous epoxy resin dispersion prepared through the semi-esterification reaction between a dicarboxylic acid anhydride and the secondary hydroxy group of an epoxy resin, followed by neutralization of the carboxylic acid thus introduced into the epoxy resin with a tertiary amine and then adding only water, without the need of any emulsifier, to the resulting hydrophilic amine salt of the carboxylic acid. The stable aqueous epoxy resin contains both carboxyl and epoxy groups which are reactive functional groups. Also disclosed is a “single-pack” curable aqueous epoxy resin system “cross-linkable” at normal temperature prepared by adding a compound containing polyaziridine as a cross-linking agent into the aqueous epoxy resin dispersion. Upon drying, the liberated carboxyl group in the aqueous epoxy resin reacts with the polyaziridine to form an amino ester via a ring opening reaction.Type: GrantFiled: October 29, 1999Date of Patent: September 18, 2001Assignee: Chinese Petroleum Corp.Inventors: Tsorng-Wen Chen, Jen-Taut Yeh, Kan-Nan Chen, Yun-Shan Lin
