Abstract
A method for producing a composition containing low molecular weight polytetrafluoroethylene, the method including: (I) irradiating a composition containing high molecular weight polytetrafluoroethylene with ionizing radiation to obtain a composition containing low molecular weight polytetrafluoroethylene having a melt viscosity at 380° C. in the range of 1.0×10to 7.0×10Pa·s; and (II) carrying out fluorination treatment on the composition containing low molecular weight polytetrafluoroethylene obtained above.
