Polycarbonate manufacturing method |
| abstract |
(57) [Summary] [Structure] When melt-polycondensing a divalent hydroxy compound and a carbonic acid diester in the presence of a transesterification catalyst to produce a polycarbonate, the above mixture is supplied to a tank-type reaction tank to obtain a molten state. 1 produced by the reaction under The first polycondensation reaction step of removing the valent hydroxy compound and the unreacted monomer to carry out a polycondensation reaction to obtain a prepolymer, and the prepolymer obtained in the first polycondensation reaction step from a molten state to a solid state And a second polycondensation reaction step in which the above solid prepolymer is melted and supplied to a horizontal polycondensation reaction tank to carry out a polycondensation reaction to obtain a high-molecular weight polycarbonate. Method for producing polycarbonate. [Effect] A linear high-molecular-weight polycarbonate having excellent heat resistance, hue, and impact resistance is provided. |
