Fluorine-containing copolymer |
| abstract |
Provided is a fluorine-containing copolymer including a tetrafluoroethylene unit, a hexafluoropropylene unit, and a perfluoro(propyl vinyl ether) unit. The contained amount of the hexafluoropropylene unit is 9.5-11.4 mass% with respect to the total monomer units. The contained amount of the perfluoro(propyl vinyl ether) unit is 0.5-1.6 mass% with respect to the total monomer units. The melt flow rate of the fluorine-containing copolymer at 372°C is 4.1-6.9 g/10 minutes. The total number of carbonyl group-containing terminal groups, -CF=CF 2 , and -CH 2 OH is 90 or less per 10 6 main chain carbon atoms. |
