摘要: A method of decomposing a polycarbonate with water in a supercritical or subcritical state. A high-purity dihydroxy compound which is a constituent component of the polycarbonate can be recovered at a high yield by this decomposition method. This decomposition method is environment-friendly because it does not use an organic solvent, easy to be carried out, has a high decomposition rate and rarely causes a side reaction.

摘要: The present invention concerns an electric double layer capacitor, wherein to increase capacitance, each electrode is formed from activated carbon having an average particle size of 0.1 to 1.0 μm. Alternatively, to prevent electrode short-circuiting, each electrode is constructed from an electrode layer sheet having an electrode layer formed from activated carbon whose specific area is 500 to 2500 m2/g and whose cumulative particle size (D90) is 0.8 to 6 μm.
