| titleOfInvention | Polycondensation resin recycling method |
| abstract | (57) [Problem] To provide a recycling method for renewing a waste polycondensable resin that can be melted with high energy efficiency by using a melt polymerization apparatus. SOLUTION: In the method for recycling a polycondensation resin, a waste polycondensation resin is added to a melt polymerization apparatus, and a polycondensation reaction is allowed to proceed. When producing a polycondensation resin using a continuous melt polycondensation apparatus in which a plurality of polymerization tanks are connected, a waste polycondensation resin is supplied to an arbitrary portion of the polycondensation apparatus, and is produced by the apparatus. Exchange reaction between the resin and the supplied waste resin or / And a method for recycling a polycondensation resin characterized by allowing a polycondensation reaction to proceed. When producing a polycondensation-based resin using a continuous melt polycondensation apparatus in which a plurality of polymerization tanks are connected, the polycondensation resin is supplied to the exit side of the polymerization tank in the previous polycondensation step (oligomerization step), and the second-stage polycondensation apparatus is used. A polycondensation resin recycling method, wherein an exchange reaction and / or a polycondensation reaction between the resin produced in step (a) and the supplied waste resin proceeds. |
