Synthetic example 1
[0135] Add 392kg of demineralized pure water into a jacketed stirring polymerization tank capable of holding 1320kg of water, fully replace the inner space with pure nitrogen, and then vacuum out the nitrogen. Then press 307kg of octafluorocyclobutane, 5.8kg of chlorotrifluoroethylene [CTFE], 49.6kg of tetrafluoroethylene [TFE], and 27.7kg of perfluoro(propyl vinyl ether) [PPVE], and adjust the temperature to 35°C , start stirring. 0.8 kg of a 50% by mass methanol solution of di-n-propylperoxydicarbonate [NPP] was added thereto as a polymerization initiator to initiate polymerization. During the polymerization, add the mixed monomer (CTFE:TFE:PPVE (mol%)=25:73:2) whose composition is adjusted to be the same as that of the required copolymer to maintain the pressure in the polymerization tank at 0.80MPa, and simultaneously polymerize to The ratio of the total additional amount to the solvent was 70% by mass. Then, the remaining gas in the polymerization tank was discharged, an...

[0137] Add 392kg of demineralized pure water into a jacketed stirring polymerization tank capable of holding 1320kg of water, fully replace the inner space with pure nitrogen, and then vacuum out the nitrogen. Then press in 307kg of octafluorocyclobutane, 8.3kg of chlorotrifluoroethylene [CTFE], 49.6kg of tetrafluoroethylene [TFE], and 29.0kg of perfluoro(propyl vinyl ether) [PPVE], and adjust the temperature to 35°C , start stirring. 0.8 kg of a 50% by mass methanol solution of di-n-propylperoxydicarbonate [NPP] was added thereto as a polymerization initiator to initiate polymerization. During the polymerization, add the mixed monomer (CTFE:TFE:PPVE (mol%)=28:70:2) whose composition is adjusted to be the same as that of the required copolymer to maintain the pressure in the polymerization tank at 0.80MPa, and simultaneously polymerize to The ratio of the total additional amount to the solvent was 70% by mass. Then, the remaining gas in the polymerization tank was discharged,...

[0139] Add 392kg of demineralized pure water into a jacketed stirring polymerization tank capable of holding 1320kg of water, fully replace the inner space with pure nitrogen, and then vacuum out the nitrogen. Then press in 307kg of octafluorocyclobutane, 18kg of chlorotrifluoroethylene [CTFE], 35kg of tetrafluoroethylene [TFE], and 22kg of perfluoro(propyl vinyl ether) [PPVE], adjust the temperature to 35°C, and start stirring . 3.2 kg of a 50% by mass methanol solution of di-n-propylperoxydicarbonate [NPP] as a polymerization initiator was added thereto to initiate polymerization. During the polymerization, add the mixed monomer (CTFE:TFE:PPVE (mol%)=37:61:2) whose composition is adjusted to be the same as that of the required copolymer to maintain the pressure in the polymerization tank at 0.69MPa, and simultaneously polymerize to The ratio of the total additional amount to the solvent was 70% by mass. Then, the remaining gas in the polymerization tank was discharged, and ...
