Polymerization of Epoxides and Reactions of Trifluoramine Oxide.

Abstract

Several methods of epoxide polymerization have been studied. Low molecular weight epichlorohydrin-ethylene oxide copolymers were produced by boron trifluoride initiation. High molecular weight polymers were synthesized using an aluminum coordination catalyst. In an attempt to obtain the desired molecular weights for liquid prepolymers, various aluminum catalyst modifications were used, but the molecular weights of the polymers were too large. Glycidyldinitrofluoroethoxide was polymerized by an aluminum-water catalyst to a high molecular weight material that is now being characterized. Reactions of trifluoroamine oxide salts with some aliphatic and aromatic compounds were studied. Interactions between trifluoroamine and Lewis acids, boron trifluoride and arsenic pentafluoride, formed the salts used. A range of reactivity between these salts and organic compounds was observed that was related to the nature of the substituents present. When a reaction took place, charring without oxydifluoroamine synthesis was the primary occurrence. No evidence for new oxydifluoroamines was obtained.
