Polymerization method for polyester resin, polyester resin composition, and polyester film |
| abstract |
A polymerization method for a polyester resin, the method including: an esterification reaction step which includes at least polymerizing an aromatic dicarboxylic acid and an aliphatic diol in the presence of a catalyst containing a titanium compound including an organic chelated titanium complex having an organic acid as a ligand, and adding the organic chelated titanium complex, a magnesium compound, and a pentavalent phosphoric acid ester which does not have an aromatic ring as a substituent, in this order; and a condensation polymerization step of subjecting an esterification reaction product produced by the esterification reaction step to a condensation polymerization reaction. |
