  • Patent number: 7071252
    Abstract: Monoesters derived from a dihydric alcohol and a carboxylic acid such as benzoic acid are secondary plasticizers for non-aqueous and solventless plastisols containing primary plasticizers that do not contain unreacted alkanol groups.
    Type: Grant
    Filed: September 11, 2003
    Date of Patent: July 4, 2006
    Assignee: Velsicol Chemical Corporation
    Inventors: Bruce E. Stanhope, William D. Arendt, Jiamin Lang
  • Publication number: 20040132882

  • Patent number: 6706806
    Abstract: A portion of the repeating units in polyesters useful as plasticizers for rigid organic polymers are derived from diethylene glycol and at least one dicarboxylic acid. The percentage of these repeating units that can be present in polyesters that are compatible with the organic polymer into which they are incorporated is inversely proportional to the weight average molecular weight of the polyester.
    Type: Grant
    Filed: December 20, 2000
    Date of Patent: March 16, 2004
    Assignee: Velsicol Chemical Corporation
    Inventors: Jiamin Lang, Franz Josef Luxem, Bruce E. Streeter, Bruce E. Stanhope, Eric R. Zimmermann
  • Patent number: 6689830
    Abstract: Compositions comprising at least one acrylic, vinyl acetate or epoxide polymer or copolymer as a film-forming ingredient and an ester of benzoic acid wherein the alcohol portion of the ester is alkyl and contains eight carbon atoms exhibit unexpected improvements in film-forming and applied film properties. In preferred compositions this alcohol portion is 2-ethylhexyl. Additionally, the preferred benzoic acid ester frequently interacts synergistically with benzoic acid esters derived from oligomeric ethylene glycols.
