| abstract | (57) [Summary] [Object] The present invention can provide a polyester having a small amount of acetaldehyde content and in which acetaldehyde is less likely to increase even when molding a bottle or the like, Moreover, the present invention provides a method for producing polyester in which the solid-phase polycondensation step can be omitted. [Structure] The method for producing a polyester according to the present invention comprises: [A] a liquid phase for producing a polyester having an intrinsic viscosity of 0.7 to 1.5 dl / g measured in o-chlorophenol by liquid phase polycondensation. The method includes a polycondensation step, a [B] pre-crystallization step, a [C] heating step of heating to a temperature of 160 to 200 ° C. for 1 to 10 hours, and a [D] hot water treatment step. In B] and [C], The intrinsic viscosity of the polyester is not substantially increased, and (ii) the obtained polyester has an acetaldehyde content of 10 ppm or less. |
