摘要： Provided is a method for producing low-molecular-weight polytetrafluoroethylene which is less likely to generate C6-C14 perfluorocarboxylic acids and salts thereof. The disclosure relates to a method for producing low-molecular-weight polytetrafluoroethylene having a melt viscosity at 380° C. of 1.0×102 to 7.0×105 Pa·s. The method includes (1) irradiating high-molecular-weight polytetrafluoroethylene with radiation in a substantially oxygen-free state and decomposing the high-molecular-weight polytetrafluoroethylene into a low-molecular-weight component and (2) deactivating, in a substantially oxygen-free state, at least part of main-chain radicals and end radicals generated by the irradiation and providing the low-molecular-weight polytetrafluoroethylene.

摘要： A method for producing low molecular weight polytetrafluoroethylene having a melt viscosity at 380° C. of 1.0×102 to 7.0×105 Pa·s. The method includes: (1) irradiating high molecular weight polytetrafluoroethylene with radiation in the presence of a substance capable of generating a free hydrogen atom and decomposing the high molecular weight polytetrafluoroethylene into a low molecular weight component; and (2) deactivating at least part of main-chain radicals and end radicals generated by the irradiation and providing the low molecular weight polytetrafluoroethylene. Also disclosed is a composition containing the low molecular weight polytetrafluoroethylene and a low molecular weight polytetrafluoroethylene.

摘要： The present invention aims to provide a pseudo sunlight irradiation apparatus capable of artificially reproducing the daily path of the sun and reproducing the daily insolation. A pseudo sunlight irradiation apparatus (10) of the present invention includes a light source (1), a spectrum correction filter (2) configured to make the spectral distribution of light emitted from the light source approximate to the spectral distribution of the sunlight, and a stage (3) configured to mount a sample (5). The stage includes an angle adjuster (6) configured to adjust the incident angle of light applied to the sample.
