  • Epoxidized mixed mellitate compounds
    Patent number: 4070350
    Abstract: Epoxidized mixed mellitate compounds useful as plasticizers for vinyl polymers such as polyvinyl chloride and which have markedly improved resistance to oils and hydrocarbon extraction have been prepared. The mixed mellitate plasticizers of this invention are trimellitates wherein two of the ester moieties are simple esters derived from monofunctional alcohols with the third ester moiety being a complex ester obtained by the reaction of a diol with an unsaturated monobasic acid subsequently epoxidized at the site of unsaturation.
    Type: Grant
    Filed: November 20, 1973
    Date of Patent: January 24, 1978
    Assignee: Emery Industries, Inc.
    Inventors: Alfred Johannes Dieterman, Roland Hendrick Riem

  • Vinyl resins plasticized with mixed mellitate compounds
    Patent number: 3956220
    Abstract: Mixed mellitate compounds useful as plasticizers for vinyl polymers, such as polyvinyl chloride homopolymers and copolymers, which have increased resistance to hydrocarbons have been prepared. The mixed mellitates of this invention are derived from trimellitic acid and trimellitic anhydride and contain two ester moieties derived from monofunctional alcohols and a third complex ester group obtained either by the reaction of a diol, a dibasic acid and a monofunctional alcohol or by the reaction of a diol and a monobasic acid.
