Patent number: 5976706Abstract: Polyesterdiols having low viscosities of less than 3500 cps, high content of non-volatile matter in excess of 96 wt %, and narrow molecular weight distribution of less than about 1.4 are prepared by esterification of one or more aliphatic dicarboxylic acids or ester derivatives thereof using at least a 1.5 molar excess of one or more aliphatic diols until an acid number of less than 20 is achieved, and stripping excess diol from the polyesterdiol reaction product. Where esterification catalyst is used, catalyst is substantially removed prior to stripping excess unreacted diol from polyesterdiol reaction product. The polyesterdiols so produced are useful as (i) curable components in thermosettable resin compositions, particularly compositions essentially free of volatile organic solvent and also containing a crosslinking agent and a reactive hardening agent: and/or (ii) useful as coatings, paints and adhesives, providing coatings with very low content of volatile organic compounds.Type: GrantFiled: July 27, 1998Date of Patent: November 2, 1999Assignee: Exxon Chemical Patents Inc.Inventors: Albert Ilya Yezrielev, Konstantinos R. Rigopoulos, Richard William Ryan, Karen K. Kuo, George Andrew Knudsen

Patent number: 5972809Abstract: The present invention provides a waterborne coating composition which includes a polymeric film-forming resin. The polymeric film-forming resin includes a dispersion of polymeric microparticles prepared by forming, in aqueous medium, a mixture of: (a) an unsaturated, substantially hydrophobic polyester component, and (b) an ethylenically unsaturated monomer component. With various hydrophobic polyesters, the ethylenically unsaturated monomer component of the polymeric film-forming resin includes: (a) an acrylamide or methacrylamide with N-methylol or N-alkoxymethyl functionality, (b) an alpha-beta ethylenically unsaturated compound with carboxyl functionality, and (c) an alpha-beta ethylenically unsaturated compound with no additional reactive functionality. Such a waterborne coating composition has a low V.O.C., provides added stiffness, does not block, and can be applied in such a manner that it does not substantially mask the texture of the nonwoven fabrics and/or textiles over which it is applied.Type: GrantFiled: February 2, 1998Date of Patent: October 26, 1999Assignee: PPG Industries Ohio, Inc.Inventors: Dennis L. Faler, James R. Franks, Roxalana L. Martin

Patent number: 5959028Abstract: A resin composition curable through a Michael reaction between (a) a component having a plurality of .alpha.,.beta.-unsaturate carbonyl groups and (b) a component having a plurality of activated methylene group in the presence of a catalyst is disclosed. The activated methylene component is a polymer of an asymmetric malonate ester in which one of carboxyl groups is esterified with an alkanol while the other carboxyl group is esterified with hydroxyalkyl (meth) acrylate or polyoxyalkylene glycol mono(meth)acrylate.Type: GrantFiled: May 21, 1997Date of Patent: September 28, 1999Assignee: Nippon Paint Co., Ltd.Inventors: Takashi Irie, Kei Aoki

Patent number: 5952436Abstract: A general approach to making water-resistant polyetherester resins and thermosets is disclosed. In one aspect, an unsaturated polyetherester resin prepared by inserting a carboxylic acid derivative into a polyether is co-cured with a vinyl monomer and a di- or polyisocyanate to give a water-resistant, thermoset that has excellent dimensional stability, flexibility, and strength properties. Processes for making low-viscosity resins that give thermosets with good water resistance are also described. In one process, an unsaturated polyetherester resin intermediate reacts with a mono-functional isocyanate or fatty alcohol to produce an easy-to-formulate, low-viscosity, low-molecular-weight capped resin.Type: GrantFiled: January 13, 1998Date of Patent: September 14, 1999Assignee: Arco Chemical Technology, L.P.Inventors: Gangfeng Cai, Jeffrey A.
