Reactive Plasticizers for High Temperature Quinoxaline Thermoplastics

Abstract

This report is concerned with a novel approach to the processing of high temperature thermoplastics. A series of bis(ethynylquinoxaline) monomers were prepared to demonstrate the feasibility of using reactive plasticizers in the processing of polyphenylquinoxaline thermoplastics. The monomers were prepared by the reaction of 4(3-ethynylphenoxy)-o-phenylenediamine with various aromatic 1,2-dicarbonyl compounds in m-cresol. The reactive plasticizer lowers the effective softening point of the thermoplastic resin during processing and then becomes dormant by reacting with itself or the host thermoplastic. Mixtures of monomer and thermoplastic were studied with respect to compatibility, Tg depression and plasticizer deactivation.
