摘要： A tetrafluoroethylene polymer is produced by polymerizing tetrafluoroethylene in the presence of an aqueous medium and a polymerization initiator, wherein the content of impurities (e.g. a saturated compound such as CH2F2 or CHF3 and an unsaturated compound such as CF2═CFH, CF2═CH2, CF2═CFCl or CF2═CHCl) in the tetrafluoroethylene is not more than 100 ppm. By this method, PTFE which is uniform and stretchable at a high stretch ratio and which is excellent in the fibrillation property and has a high break strength, can be obtained.
