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.
