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.
