  • Plasticizer compositions for non-aqueous plastisols
    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
  • Plastisol compositions comprising vinyl chloride polymers and mixtures of aromatic and aliphatic esters of diols as plasticizers
    Patent number: 6933337
    Abstract: Mixtures of esters produced by reacting a mixture of aromatic and aliphatic monocarboxylic acids with a diol containing from 2 to 12 carbon atoms are effective plasticizers for plastisols containing dispersion grade polymers of vinyl chloride. The freezing point of the present ester mixtures and their efficacy as plasticizers can be varied by adjusting the type and relative concentration of the aliphatic acid used to prepare the plasticizer. The ester mixtures can also be used as plasticizers for other organic polymers.

  • Polyester plasticizers for halogen-containing polymers
    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.

  • Benzoate/alkanoate ester compositions
    Publication number: 20030023112
    Abstract: Mixtures of esters produced by reacting an aromatic and an aliphatic monocarboxylic acid with a stoichiometric quantity of a diol are effective plasticizers for polyvinyl chloride and other rigid organic polymers. The freezing point of the mixtures and the efficacy of the present ester mixtures as plasticizers can be varied by adjusting the type and molar ratio of the two types of acids used to prepare the ester mixture.
