Abstract
Polyesters are prepared by the reaction of an alkyl ester of a dicarboxylic acid and certain polyoxyalkylated polyols having the formula: ##STR1## wherein x and y are integers such that the oxyethylene content of the polyol is between 10% and 90% by weight and the oxypropylene content of the polyol is between 90% and 10% by weight. The polyesters are particularly useful in the preparation of antistatic polymer compositions.
