| titleOfInvention | Polyester resin composition production method, method for regenerating recovered polyester resin, and polyester resin composition |
| abstract | Provided is a method for producing a polyester resin composition (C) in which coloring and reduction in molecular weight are unlikely to occur even when being recycled multiple times using used polyester resins in which at least one selected from an antimony compound, a titanium compound, or a germanium compound is used as a polymerization catalyst. The method comprises a step for mixing a recovered polyester resin (A) and a polyester resin (B) containing an aluminum compound and a phosphorus compound. The polyester resin (A) satisfies (1)-(3). In the polyester resin (B), the contained amount of aluminum elements and the contained amount of phosphorus elements in the polyester resin (B), and residual mole ratio of phosphorus elements with respect to aluminum elements satisfy predetermined values. (1) The polyester resin (A) contains at least one element selected from among antimony, titanium, and germanium. (2) The polyester resin (A) has a total content of antimony, titanium, and germanium elements of 2-500 mass ppm. (3) The polyester resin (A) has an intrinsic viscosity of 0.5-0.8 dl/g. |
