Abstract
This invention relates to high molecular weight polyester resin compositions which are uniquely stable under hydrolytic conditions. The polyester resin compositions are produced by the condensation of a dihydric polyol with a sterically-hindered neo-acid derivative such as .alpha.,.alpha.,.alpha.',.alpha.'-tetramethyl-p-phenylenediacetic acid.
