Meltable Bifunctional Quinoxaline Monomer and Preparation of a Polymer Therefrom.

reportActive / Technical Report | Accession Number: ADD003552 | Need Help?

Abstract:

A high molecular weight polyphenylamide-quinoxaline is prepared by heating a bifunctional monomer to a temperature above the melting point of the monomer but below the decomposition temperature of the polyphenylamide-quinoxaline Ca. 475-490 C. This melt polymerization of the bifunctional monomer produces strong, low void adhesive joints.
