Method of preparing polycarbonate resin |
| abstract |
A method of preparing a polycarbonate resin having improved thermal stability is provided. The method includes: mixing polycarbonate having hydroxy terminal groups and a end terminator, a compound of formula (1) (refer to the detailed description section) at normal temperature and pressure to obtain a mixture; and performing a melt reaction on the mixture at 250-320° C. and reduced pressure to highly reduce the final concentration of the hydroxy terminal groups of the polycarbonate resin. |
