Process for the preparation of polycarbonate by microwave |
| abstract |
The present invention relates to a method for producing a polycarbonate resin using microwave, and more particularly, in a method for producing a polycarbonate resin in which solid phase polymerization is carried out by crystallizing a prepolymer polymerized from an aromatic dihydroxy compound and a diaryl carbonate. Preparing a prepolymer having a specific range of viscosity average molecular weight; Crystallizing the prepolymer into crystalline particles to have a specific range of crystallinity; The present invention relates to a method for producing a high molecular weight polycarbonate resin having excellent quality in a short time by solid phase polymerization while applying microwaves having a frequency of 900 MHz to 2.45 GHz to the prepolymer crystalline particles. |
