| titleOfInvention | Production method and powder of low molecular weight polytetrafluoroethylene |
| abstract | The present invention provides a method for producing a low molecular weight polytetrafluoroethylene in which perfluorocarboxylic acids having 6 to 14 carbon atoms and salts thereof are difficult to produce. A high molecular weight polytetrafluoroethylene and a mixed gas containing an inert gas and oxygen and containing 1 to 10% by volume of oxygen with respect to the total of the inert gas and oxygen are charged into a sealed container. Low molecular weight polytetrafluoro having a melt viscosity at 380 ° C. of 1.0 × 10 2 to 7.0 × 10 5 Pa · s by irradiating the high molecular weight polytetrafluoroethylene with radiation in the step (1) The manufacturing method of the low molecular weight polytetrafluoroethylene characterized by including the process (2) which obtains ethylene.
