  • Sealant compositions having a novel plasticizer
    Patent number: 8784989
    Abstract: A sealant composition having from about 0.1 to about 90 weight % of a polymer selected from the group consisting of butyls, acrylics, urethanes, polysulfides, and silicone modified polymers, and at least one C4 to C8 alkyl terephthalate.
    Type: Grant
    Filed: August 29, 2007
    Date of Patent: July 22, 2014
    Assignee: Eastman Chemical Company
    Inventors: Mark R Kettner, Martin James Stimpson, Mark Stephen Holt, Russell Lynn Whitson, James Duncan Pont
  • Terephthalates as plasticizers in vinyl acetate polymer compositions
    Patent number: 8088854
    Abstract: An aqueous composition adhesive composition comprising a vinyl acetate polymer and a plasticizer having the general formula: wherein R1 and R2 are independently selected from the group consisting of saturated straight or branched and unsubstituted alkyl or cycloalkyl groups having from 4 to 8 carbon atoms.
    Type: Grant
    Filed: August 29, 2007
    Date of Patent: January 3, 2012
    Assignee: Eastman Chemical Company
    Inventors: Martin James Stimpson, Mark Stephen Holt
  • High solvating cyclohexane dicarboxylate diesters plasticizers
    Patent number: 7973194
    Abstract: Diesters of 1,4-cyclohexane dicarboxylate are surprisingly more efficient PVC plasticizers and fuse PVC faster and at a lower temperature than similar phthalates or terephthalate diesters. Hydrogenated orthophthalate diesters are slower fusing, i.e., require higher temperatures, than do the corresponding orthophthalate diesters.

  • ACRYLIC PLASTISOL VISCOSITY REDUCERS
    Publication number: 20090124737
    Abstract: Low VOC viscosity reducer (LVVR) compounds useful for reducing the viscosity of plastisol compositions. The acrylic plastisol compositions are combined with a viscosity reducing compound which is derived from esters of compounds such as 2,2,4-trimethyl-1,3-pentane diol (TMPD).

  • Liquid glycol benzoate compositions and polymer compositions containing same
    Patent number: 6184278
    Abstract: The present invention relates to organic polymer compositions, containing liquid ester compositions as plastisizers, said compositions comprising mixtures of esters derived from (a) diethylene glycol and triethylene glycol and (b) benzoic or toluic acid, wherein the freezing point of the ester mixture is below the freezing points of the constituent esters when the relative concentrations of the constituent esters are within specified limits.
    Type: Grant
    Filed: December 7, 1998
    Date of Patent: February 6, 2001
    Assignee: Velsicol Chemical Corporation
    Inventors: William David Arendt, Thomas Joseph Bohnert, Mark Stephen Holt
  • Liquid glycol benzoate compositions
    Patent number: 5990214
    Abstract: The present invention relates to liquid compositions comprising mixtures of esters derived from a) diethylene glycol and triethylene glycol and b) benzoic or toluic acid. The freezing point of the ester mixture is below the freezing points of the constituent esters when the relative concentrations of the constituent esters are within specified limits. The invention also relates oils and lubricants containing the present liquid ester compositions as plasticizing additives.
