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 produced during injection molding is specifically small and the acetaldehyde content in a molded product is reduced. An injection molding machine or an extrusion molding machine is used, and a polyester resin (a) having a water content of less than 60 ppm by weight is used as a raw material, and a raw material for a screw in the molding machine is supplied from a raw material charging hopper attached to the molding machine. In any part up to the part, water and / or a liquid containing water is added to the polyester resin (a), and at that time, water relative to the weight of the polyester resin (a) supplied to the molding machine The addition ratio is adjusted to 30 ppm to 2,000 ppm by weight. [Selection figure] None |
