A new electroactive polyaryletherketone containing benzonitrile(EPEEK-CN) was synthesized from 2,6-difluorobenzonitrile,p-benzenediol and difluoromonomer containing phenyl-capped aniline tetramer segment,via ternary polycondensation.The obtained EPEEK-CN shows certain extent solubility in organic solvents,and its film casted from DMAc solution exhibits interesting electrical,mechanical and dielectric properties.
