| 摘要 |
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.
