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.
