Embodiment 1
[0082] Carried out in a 10L high-pressure polymerization reactor, the total weight of vinylidene fluoride and hexafluoropropylene added in this embodiment is 2.3Kg, and the specific steps are:
[0083] A1, add 5L deionized water, 4g diiodomethane and 10g perfluoropolyether carboxylate ammonium salt (10wt%) in the high-pressure polymerization reactor, evacuate nitrogen replacement, reduce the oxygen content in the high-pressure polymerization reactor to less than 25ppm, And the temperature of the reactor was raised to 85°C;
[0084] A2. Add initial monomers (vinylidene fluoride and hexafluoropropylene) to the high-pressure polymerization reactor with a compressor until the pressure in the high-pressure polymerization reactor is 2.0Mpa, start stirring, and adjust the rotation speed to 98rpm;
[0085] A3, when the mixture in the autoclave polymerization reactor is heated to 90 DEG C, add 4g initiator ammonium persulfate solution (10wt%), start polymerization reaction; The molar p...
