The sulfonated polyether ketone ketones(S-PEKK) with various sulfonation degree were synthesized by reaction of PEKK with sulfuric acid as sulfonating agent and solvent.The effect of concentration of sulfuric acid and PEKK reaction temperature and time on sulfonating degree and ion exchange capacity of products were investigated.S-PEKKs were characterized by IR
DSC and X ray diffraction.The experimental results show that S-PEKKs have the expected structure.Crystallinity and melt temprature of S-PEKKs decrease with the increasing of sulfonating degree of S-PEKK.
