| description | The invention discloses sulfuryl bridge connection side chain sulfonated polyimide, a preparation method thereof and a method for preparing proton exchange membranes by applying the sulfonated polyimide. The sulfuryl bridge connection side chain sulfonated polyimide is structurally characterized in that a side chain with a sulfonic acid group is connected onto a polyimide main chain through sulfuryl serving as a bridge connection group, the sulfuryl serves as the bridge connection group, so that flexibility of the side chain and acidity of the sulfonic acid group are ensured, and an obtained polymer has high molecular weight and good hydrolytic stability. A preparation process of the sulfonated polyimide is simple and applicable to industrial production, and reaction conditions are easily operated and controlled. The proton exchange membranes prepared by the sulfuryl bridge connection side chain sulfonated polyimide have high proton conductivity and potential application prospects.
