Synthesis and polymerization of a novel perfluorinated monomer

Perfluoro(5-methylene-2,2-dimethyl-1,3-dioxolane) (1) was synthesized by utilizing a direct fluorination reaction. Compound 1 was an entirely novel monomer with difluoromethylene at position 5 on the dioxolane ring as an unprecedented polymerization site. It successfully polymerized with tetrafluoroethylene to afford copolymers, which had Tg values in the range of 60-90 °C. The content of monomer 1 in the obtained polymers was less than 20 mol%, which seemed insufficient for giving various unique properties to polymers. However, each polymer was expected to be a superior material because of their advanced thermal stability. Comparison with copolymers of 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole and tetrafluoroethylene is also discussed.

Epoxides and their preparation

Process comprising heating a dioxole at 100°-400° C. for a sufficient time to convert the dioxole to an epoxide, for example, bis-2,2-trifluoromethyl-4,5-difluoro-1,3-dioxole to 2,3-epoxy-3-trifluoromethyl-4-trifluorobutyryl fluoride.
