Meltable Bifunctional Quinoxaline Monomers and Preparation of a Polymers Therefrom.
Abstract
Accordingly, one object of this invention is to provide novel bifunctional quinoxaline monomers. Another object of this invention is to provide bifunctional quinoxalines which polymerize upon melting to form polyphenylamide-quinoxalines. A further object of this invention is to provide bifunctional monomers which inherently contain the stoichiometry required for the attainment of high molecular weight polymers. Still another object of this invention is to provide a solventless process for synthesizing high molecular weight polyphenylamide-quinoxalines. A still further object of this invention is to provide solvent free prepregs and adhesive joints. Yet another object of this invention is to provide prepregs and adhesive joints having low void contents. Yet a further object of this invention is to provide polymers having high strengthes and good thermal stabilities. Another object of this invention is to provide improved wetting of fibers and metal surfaces by polymers in prepregs and adhesive joints. (Author)
