Polybenzimidazole containing ether ketone/ether sulfone structure as well as sulfonated polymer and preparation method thereof

Abstract

The invention discloses polybenzimidazole containing an ether ketone/ether sulfone structure and a sulphonated polymer and a preparation method thereof. The chain structure of a polybenzimidazole polymer containing the ether ketone/ether sulfone structure also has the structure of ether ketone or ether ether ketone or ether sulfone and imidazole; besides the structure of ether ketone or ether ether ketone, the chain structure of the sulphonated polymer of the polybenzimidazole containing ether ketone/ether sulfone structure also has the structure of sulfonic group and imidazole. The preparation method adopts the steps that a bisphenol-bisbenzimidazole monomer and a difluoro monomer or a fluoride bearing monomer are used as the raw material, anhydrous sodium carbonate or anhydrous potassium carbonate is used as the catalyst, nucleophilic condensation polymerization reaction is performed in an aprotic polar solvent, and after the reaction liquid is post-treated, the polybenzimidazole polymer of the sulphonated polymer containing ether ketone/ether sulfone structure is obtained. The polymer obtained through the invention has good oxidation resistance, thermostability, acidproof and alkali proof stability, and alcohol inhibition performance, and the synthetic method is simple, thereby the polybenzimidazole has broad application prospect.
