Method for producing polyethylene terephthalate resin and polyester resin molding |
| abstract |
Disclosed is a polyethylene terephthalate resin in which the amount of acetaldehyde by-product during melt molding is small and the acetaldehyde content in a molded body is reduced. An intrinsic viscosity [η 2 ] is 0.70 dl / g or more and 1.50 dl / g or less, an acetaldehyde content [AA 0 (weight ppm)] is 10 weight ppm or less, and a water content is 30 ± 20. The acetaldehyde content [AA 1 (wt ppm)] of the molded product obtained by adjusting the weight to ppm by weight and injection molding at 280 ° C. and the moisture content were adjusted to 120 ± 20 wt ppm and injected at 280 ° C. Polyethylene terephthalate resin in which the acetaldehyde content [AA 2 (weight ppm)] of the molded product obtained by molding satisfies the following formula (1). [Expression 1] [Selection figure] None |
