The invention discloses a sulfonated poly(aryle ether ketone) copolymer containing benzothiazole groups and a preparation method of the sulfonated poly(aryle ether ketone) copolymer. The copolymer is prepared through steps as follows: bisphenol monomers, 2,6-dichlorobenzothiazole, 4,4'-difluorobenzophenone and 3,3'-disulfonic acid sodium salt-4,4'-difluorobenzophenone are taken as raw materials, a salt-forming agent and a water-carrying agent are added after the raw materials are dissolved and mixed by a solvent, solid content of a reaction system is adjusted to be 15%-30%, the reaction system carries water for 3-6 h at the temperature of 120-140 DEG C, and reacts for 6-20 h at the temperature of 140-200 DEG C after the water-carrying agent is steamed out, a mixture is discharged to acetone or distilled water after the reaction is finished, a coarse product is obtained and washed, and the sulfonated poly(aryle ether ketone) copolymer containing the benzothiazole groups is obtained. An electrolyte membrane prepared from the copolymer has better dimensional stability, lower methanol permeability, higher antioxidative stability and good proton conduction performance, and compared with a traditional aromatic polyelectrolyte membrane, the electrolyte membrane prepared from the copolymer is a novel proton exchange membrane material with excellent performance and has good application prospect in the field of the electrolyte membrane of a fuel cell.

The invention belongs to the field of high polymer materials and particularly relates to sulfonated polyarylether sulfone containing a pyridine group and a preparation method of the sulfonated polyarylether sulfone. According to the preparation method, dichloropyridine such as 3,5-dichloropyridine is taken as a monomer, and the feeding proportion of sulfonated monomers to non-sulfonated monomers is adjusted, so as to prepare polyarylether sulfone with different sulfonating degrees by virtue of nucleophilic condensation polymerization; and meanwhile, the feeding proportion of pyridine monomers is adjusted, so as to prepare sulfonated polyarylether sulfone with different pyridine content. A sulfonated polyarylether sulfone copolymer film containing the pyridine group has good dimensional stability, chemical stability and alcohol-rejecting ability and further has potential application prospect in the field of fuel cell polymer electrolyte membranes.
