Method for producing polytetrafluoroethylene fine powder |
| abstract |
The present invention provides a method for producing a polytetrafluoroethylene fine powder, which comprises emulsion polymerizing tetrafluoroethylene in the presence of an aqueous medium, a fluorinated surfactant and a radical polymerization initiator to produce an aqueous polytetrafluoroethylene emulsion, mixing and coagulating the aqueous emulsion to separate a polytetrafluoroethylene fine powder, and then drying the polytetrafluoroethylene fine powder in a wet state in an atmosphere containing ammonia. |
