| titleOfInvention | Method for producing low molecular weight polytetrafluoroethylene |
| abstract | Provided is a method for producing a low molecular weight polytetrafluoroethylene which is difficult to produce a perfluorocarboxylic acid having 6 to 14 carbon atoms and a salt thereof. The present disclosure provides a method for producing a low molecular weight polytetrafluoroethylene which is a melt viscosity of 1.0 × 10 2 ~7.0 × 10 5 Pa · s at 380 ° C., in the substantial absence of oxygen By irradiating the high molecular weight polytetrafluoroethylene with radiation, the step (1) of reducing the molecular weight of the high molecular weight polytetrafluoroethylene, and at least a part of the main chain radical and the terminal radical generated by the irradiation are substantially substantially. The present invention relates to a method for producing low molecular weight polytetrafluoroethylene, which comprises the step (2) of obtaining the low molecular weight polytetrafluoroethylene by inactivating it in the absence of oxygen. |
