Patent number: 6001922Abstract: This invention provides the preparation of water-dispersible polyester/acrylic hybrids via a two-stage emulsion polymerization process. For example, methacrylic acid and/or 2-hydroxyethyl methacrylate are copolymerized with styrene/acrylic monomers to yield a relatively hydrophilic and hydro-plasticized first stage. Subsequent additions of hydrophobic monomers to this first stage "seed" results in an inversion of the latex such that the more hydrophilic first stage is at the particle surface. This results not only in improved stability of the resulting latex without the use of additional surfactants, as evidenced by the production of reduced amounts of coagulum, while it also offers relatively low minimum filming temperatures due to the hydroplasticization of the shell of the particle. Furthermore, the use of the water-dispersible polyester results in extremely fine latex particle sizes which can significantly enhance coating properties such as film gloss and clarity.Type: GrantFiled: August 15, 1997Date of Patent: December 14, 1999Assignee: Eastman Chemical CompanyInventors: Mark Dwight Clark, Hieu Duy Phan, James Russell Salisbury, Glen Dennis Shields

Patent number: 5977215Abstract: The present invention is directed to improved aqueous dispersions containing polyurethane/vinyl polymers. The improved aqueous dispersions comprise polymer particles of a urethane prepolymer having carboxyl functionality therein and a vinyl monomer polymerized thereon, which are shelf stable and self crosslinkable at a low temperature. The polyurethanes have pendant carboxyl functionality in quaternary form and pendant epoxide groups provided by glycidyl acrylates and/or methacrylates. When the aqueous dispersions are cast as film and the water is removed, crosslinking between the carboxyl group and the epoxide group occurs.Type: GrantFiled: June 16, 1997Date of Patent: November 2, 1999Assignee: Air Products and Chemicals, Inc.Inventors: Chao-Fong Tien, Chung-Ling Mao, Jeanine M. Snyder, Adalgery Beck

Patent number: 5972158Abstract: A process of bonding a plastic is provided. The process comprises applying to a plastic surface an aqueous dispersion of a hydroxyl-functional polyurethane prepolymer obtained by:(1) reaction of:a polyol component containing a polyester polyol,a compound selected from the group of compounds containing groups capable of salt formation and at least two isocyanate-reactive groups,an isocyanate component in a stoichiometric excess, at least 20% by weight of said component consisting of tetramethyl xylylene diisocyanate, and(2) subsequent dispersion in water and at least partial reaction of the remaining NCO groups with an aminoalcohol and, optionally, subsequent chain extension. The process further comprises drying said applied aqueous dispersion to form a primer and bonding said plastic surface having said primer to a part to be joined thereto. The process is particularly useful for priming plastics such as polyvinyl chloride.Type: GrantFiled: October 15, 1996Date of Patent: October 26, 1999Assignee: Kenkel Kommanditgeselschaft auf AktienInventors: Horst Hoffmann, Hans-Georg Kinzelmann, Hans-Peter Kohlstadt

Patent number: 5973073Abstract: Two-component polyurethane coating formulations comprising an aqueous dispersion of a polyisocyanate and a neutralized, water-dispersible resin are disclosed. The neutralized, water-dispersible resin incorporates recurring units of an allylic alcohol or an alkoxylated allylic alcohol. These low-VOC formulations use commercial polyisocyanates and ordinary mixing techniques. The uniquely uniform distribution of hydroxyl groups in the resin contributes to an excellent overall balance of coating properties from the 2K system, including high gloss, hardness, impact resistance, flexibility, weatherability, and chemical resistance.Type: GrantFiled: April 6, 1998Date of Patent: October 26, 1999Assignee: ARCO Chemical Technology, L.P.Inventors: Shao-Hua Guo, Donald L. Lickei, Michael J. Morgan, James M. O'Connor
