Method for producing polytetrafluoroethylene

A method for producing polytetrafluoroethylene comprising:

• polymerizing tetrafluoroethylene in an aqueous medium in the presence of a hydrocarbon surfactant and a polymerization initiator to obtain a polytetrafluoroethylene;
• and
• adding at least one selected from the group consisting of a radical scavenger and a decomposer of the polymerization initiator after an initiation of polymerization,
• wherein an amount of the radical scavenger added is an amount corresponding to 5 to 100% (molar basis) of a polymerization initiator concentration,
• an amount of the decomposer of the polymerization initiator added is an amount corresponding to 5 to 100% (molar basis) of a polymerization initiator concentration, and
• in the polymerization, tetrafluoroethylene is polymerized substantially in the absence of a fluorine-containing surfactant.
