Polycarbonate manufacturing method and polycarbonate manufacturing apparatus |
| abstract |
(57) Abstract: The present invention provides a method for efficiently producing a polycarbonate having a high terminal blocking rate and a high molecular weight, and an apparatus used in the production method. The method includes using at least two reactors in series. An aromatic dihydroxy compound and a carbonic acid diester are subjected to a melt polycondensation reaction while continuously distilling off a by-product hydroxy compound derived from the carbonic acid diester to produce an aromatic polycarbonate. The end capping agent is introduced into the pipe (C) connecting the reactor (A) reaching the desired value and the next reactor (B), and the end capping with the polycarbonate product in a sealed state (760 mmHg or more). A method for producing a polycarbonate, which comprises mixing a phenolic compound with an agent and sealing the terminal phenolic hydroxyl group of the polycarbonate at a high temperature under reduced pressure in a reactor (B). |
