Method for producing low-molecular weight polytetrafluoroethylene, and powder |
| abstract |
A method for producing low-molecular-weight polytetrafluoroethylene which includes: (1) irradiating high-molecular-weight polytetrafluoroethylene with radiation to a dose of 250 kGy or higher substantially in the absence of oxygen to provide low-molecular-weight polytetrafluoroethylene having a melt viscosity at 380° C. of 1.0×102 to 7.0×105 Pa·s. Also disclosed is a powder containing the low-molecular-weight polytetrafluoroethylene, the powder being substantially free from any of perfluorooctanoic acid and salts thereof. |
