| titleOfInvention | Process for capping quinone-coupled polyphenylene oxides |
| abstract | ABSTRACT OF THE DISCLOSURE A process is disclosed which provides for an increase in the oxidative and/or thermal stability of quinone coupled polyphenylene oxides which comprises contacting quinone-coupled polyphenylene oxides with a capping agent in the presence of a water soluble base, and a catalytic phase transfer agent. The resulting new polymers have improved color and in combination with styrene resins provide ther-moplastic compositions having improved chemical and physical properties. |
