Abstract
A novel fluoropoly(ether ether ketone) was synthesized by nucleophilic subs titution reactions based on 2-(3 ' -trifuoromethyl)phenyl-hydroquinone(FH) and 4,4 ' -difluorobenzophenone. Studies on its properties showed that diel ectric constant of fIuoropoly(ether ether ketone)(FPEEK) was 2.7. FPEEK cou ld be dissolved in a wide range of organic solvents, such as DMF, DMAc, DMS O, 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. A series 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 copolymer s showed that the dielectric constants of fluoropoly(aryl ether ketone)s de clined linearly with content of -CF3 increasing in structure units for copo lymers.
