The Synthesis and Properties of Fluoropoly(aryl ether ketone)s

Abstract

Abstract: Anovel fluoropoly(ether ether ketone) was synthisized by nucleophilic substitution reactions based on 2-(3'-trifuoromethyl)phenyl hydroquinone(FH) and 4,4'-difluorobenzophenone. Studies on its properties showed that dielectric constant of fluoropoly(ether ether ketone)(FPEEK) was 2.7. FPEEKcould be dissolved in a wide range of organic solvents, such as DMF, DMAc, DMSO, NMP, TMS, dichloromethane, chloroform etc. and thin film of the polymer cast from chloroform was transparent, creasable and tough. Coating film had a strong adhesion force and resistance to impact with surface substrates. Aseries of copolymers of fluoropoly(aryl ether ketone)s were synthesized by nucleophilic substitution reactions based on FH, 4,4'-biphenol(BP) and 4,4'-difluorobenzophenone. Studies on the dielectric constant of copolymers showed that the dielectric constants of fluoropoly(aryl ether ketone)s declined linearly with content of —CF₃ increasing in structure units for copolymers.
