Abstract
The use of a group of diester compounds that are particularly effective as plasticizers in polyvinylchloride-resin formulations and articles made therefrom. These compounds are the diesters of alkanedicarboxylic acids and alkanolethers. They are prepared by the direct esterification reaction of dicarboxylic acids with alkanolethers or by the trans esterification reaction of diesters with the corresponding alkanolethers.
