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