| titleOfInvention | Method for producing copolymer polyester resin |
| abstract | The present invention provides a method for producing a copolyester resin capable of suppressing the fusion of polyester resin granules and efficiently crystallizing them in heat crystallization treatment of a polyester resin after melt polycondensation. . A mole% (A) of a dicarboxylic acid component other than terephthalic acid or an ester-forming derivative of terephthalic acid with respect to all dicarboxylic acid components in the copolyester resin having an ethylene terephthalate unit as a main structural repeating unit; The sum (A + B) of the diol component other than ethylene glycol to the total diol component in the copolymerized polyester resin (A + B) is more than 8 and 80 mol% or less, and at least of a titanium compound, an aluminum compound, and an antimony compound A copolyester resin characterized by using one compound as a catalyst for melt polymerization, heat-crystallizing the copolyester resin with hot water after melt polymerization and before solid-phase polymerization, and then solid-phase polymerization Manufacturing method.
