| abstract | (57) [Summary] [Purpose] Polycondensation is performed at least in the presence of a titanium compound, the amount of by-products generated during molding is small, mold contamination during molding is suppressed, and transparency is excellent. To provide a polyester resin. A dicarboxylic acid component mainly composed of an aromatic dicarboxylic acid or an ester-forming derivative thereof and a diol component mainly composed of ethylene glycol are subjected to an esterification reaction or a transesterification reaction to at least a titanium compound. a polyester resin produced by polycondensation under a cyclic trimer content of the resin in the molding body after injection molding at 280 ℃ (CT S; wt%) When, of the resin before injection molding the cyclic trimer content (CT 0; wt%) the difference between (CT S -CT 0) is a polyester resin is 0.10 wt% or less. |
