| abstract | (57) [Abstract] [Purpose] In the method of producing a polycarbonate by melt polycondensation of a divalent hydroxy compound and a bisaryl carbonate by a transesterification method, a colorless transparent high molecular weight polycarbonate is industrially produced efficiently. .. [Constitution] As a material of the reactor, a transesterification reaction is carried out using a material having a compositional quantitative relationship of Ni and / or C content of 60% or more. [Effect] A colorless and transparent high-molecular weight polycarbonate can be produced, and the obtained polycarbonate can be used for various applications in which transparency can be sufficiently exhibited. |
