Embodiment 1
[0039] Under the protection of nitrogen, 50g of perfluorobutylethylene, 15g of allyl glycidyl ether, 7.5g of ethyl acrylate and 127g of 1.6 hydrogen-containing silicone oil were mixed to obtain a mixed solution 1, and the remaining 50g of perfluorobutylethylene, 15g of alkene Propyl glycidyl ether, 7.5g ethyl acrylate and 0.075g Karstedt catalyst (1,3-divinyl-1,1,3,3-tetramethyldisiloxane platinum (0), Pt, 2% di Toluene solution) were combined and placed in an environment of 55° C. for 30 minutes of activation to obtain a mixed solution 2. After activation, the mixed solution 2 was slowly added dropwise to the mixed solution 1 while stirring, and the reaction temperature was set at 55°C. After four hours the temperature was raised to 60°C. After four hours, the reaction was completed and the stirring was continued and 5 g of S 2 c. After 1 hour, the product was vacuum filtered for 30 minutes to remove unreacted small molecules. The structural formula is as follows.

Embodiment 2
[0042] Under nitrogen protection, 50g of perfluorooctylethylene, 10g of 3-allyl-2,2-dimethyloxirane, 25g of ethyl acrylate and 84.7g of 1.6 hydrogen-containing silicone oil were mixed to obtain a mixed solution 1, The remaining 25g of perfluorobutylethylene, 10g of 3-allyl-2,2-dimethyloxirane, 25g of ethyl acrylate and 0.025g of Karstedt catalyst (1,3-divinyl-1,1, 3,3-Tetramethyldisiloxane (platinum (0), Pt, 2% xylene solution)) were combined and activated at 55°C for 30 minutes to obtain a mixed solution 2. After activation, the mixed solution 2 was slowly added dropwise to the mixed solution 1 while stirring, and the reaction temperature was set at 55°C. After four hours the temperature was raised to 60°C. After four hours, the reaction was completed and the stirring was continued and 5 g of S 2 c. After 1 hour, the product was vacuum filtered for 30 minutes to remove unreacted small molecules. The structural formula is as follows.

Embodiment 3
[0045] Under nitrogen protection, 50g of perfluorohexylethylene, 32.5g of 1,1,2-trifluoro-4,5-epoxy-1-pentene, 50g of ethyl acrylate and 254g of 1.6 hydrogen-containing silicone oil were mixed to obtain a mixed solution 1 , the remaining 50g perfluorobutylethylene, 32.5g 1,1,2-trifluoro-4,5-epoxy-1-pentene, 50g ethyl acrylate and 0.125g Karstedt catalyst (1,3-divinyl -1,1,3,3-tetramethyldisiloxane (platinum (0), Pt, 2% xylene solution) were mixed and activated at 55°C for 30 minutes to obtain a mixed solution 2. After activation, the mixed solution 2 was slowly added dropwise to the mixed solution 1 while stirring, and the reaction temperature was set at 55°C. After four hours the temperature was raised to 60°C. Four hours later, after the reaction was over, the stirring was continued and 5 g of thiophene was added dropwise. After 1 hour, the product was vacuum filtered for 30 minutes to remove unreacted small molecules. The structural formula is as follows.
