  • 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.

  • Low volatile organic content viscosity reducer
    Patent number: 7741395
    Abstract: Low VOC viscosity reducer (LVVR) compounds useful for reducing the viscosity of plastisol compositions. The plastisol compositions are combined with a viscosity reducing compound which is derived from the reaction of at least one of 2,2,4-trimethyl-1,3-pentane diol (TMPD) and 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TXOL) with at least one of a carboxylic acid or a fatty acid.
    Type: Grant
