| titleOfInvention | Solid-State Polymerization method using microwave radiation and gas flow containing vapor having high dipole moment |
| abstract | The present invention is to improve the reaction rate and by-products by using a gas containing a vapor of the liquid having a dipole moment with a heating method using a microwave in the solid phase polymerization to improve the molecular weight of the polycarbonate resin and the heat generation promotion and by-product removal effect By obtaining the synergy effect of improving the removal rate, the present invention relates to a method for efficiently producing high quality high molecular weight polycarbonate.n n n More specifically, a method for preparing a polycarbonate resin which performs a solid phase polymerization by crystallizing a polymerized prepolymer from an aromatic dihydroxy compound and a diaryl carbonate, the method comprising: preparing a prepolymer having a viscosity average molecular weight in a specific range; Making the prepolymer into particles having a specific range of sizes; The present invention relates to a method for producing a high molecular weight polycarbonate resin having excellent quality in a short time by applying a microwave to solid phase polymerization while flowing a gas containing a vapor vaporizing a liquid having a large dipole moment to the prepolymer particles. |
