| titleOfInvention | polyethylene terephthalate |
| abstract | An object of the present invention is to provide a polyester resin that produces less cyclic trimer and acetaldehyde during molding processing, suppresses corrosion of molding and polymerization equipment, and reduces quality deterioration due to mixing of metal species. It is aimed. [Solution] When polyethylene terephthalate having an intrinsic viscosity of 0.60 dl / g or more and a cyclic trimer oligomer (CT) content of 0.55 wt% or less is molded into a preform at a molding temperature of 280 ° C., Polyethylene terephthalate satisfying Formula 1 and Formula 2. ΔCT ≦ 0.10% by weight (Formula 1) Fe ≦ 1.0 ppm (Formula 2) (ΔCT represents the increased amount of the cyclic trimer oligomer contained in polyethylene terephthalate during molding, and Fe represents the weight of iron atoms contained in the polyethylene terephthalate after molding.) |
