PROCESS FOR PRODUCING POLYETHYLENE TEREPHTHALATE RESIN, MOLDED OBJECT, AND POLYETHYLENE TEREPHTALATE RESIN, MOLDED OBJECT MADE BY THESE

摘要

PURPOSE: A polyethylene terephthalate resin, a manufacturing method of a molded product thereof, and the molded product are provided to remove aldehyde generated from manufacturing polyethylene terephthalate using an aldehyde remover. CONSTITUTION: A manufacturing method of a polyethylene terephthalate resin comprises the following steps: mixing terephthalic acid and ehtylene glycol, and esterificating; forming molten polyethylene terephthalate resin by poly-condensing the outcome from the previous step; adding an aldehyde remover to the molten polyethylene terephthalate resin; and molding the molten polyethylene terephthalate resin including the aldehyde remover by extruding.
