| titleOfInvention | Process for the preparation of polycarbonate by microwave |
| abstract | The present invention relates to a process for producing a polycarbonate resin using a microwave, and more particularly, to a process for producing a polycarbonate resin which crystallizes a prepolymer polymerized from an aromatic dihydroxy compound and a diaryl carbonate to perform solid phase polymerization, Preparing a prepolymer having a specific range of viscosity average molecular weights; Crystallizing the prepolymer into crystalline particles so as to have a specific range of crystallinity; Molecular-weight polycarbonate resin with high quality in a short period of time by applying a microwave having a frequency of 900 MHz to 2.45 GHz to the prepolymer crystalline particles while performing a solid-state polymerization. |
