titleOfInvention | Method of producing polyethylene terephthalate |
abstract | An object of the present invention is to provide a polyethylene terephthalate having a low acetaldehyde content and an oligomer content of a molded article.n n n The subject of this invention is melt polycondensation using the compound represented by following General formula (I) as a polycondensation catalyst as a manufacturing method of a polyethylene terephthalate, and intrinsic viscosity is 0.48-0.53 cc / g, terminal carboxyl A process of obtaining a melt polycondensation polyethylene terephthalate having a number of 14 to 22 mmol / kg, and further solidifying the polycondensation of the melt polycondensation polyethylene terephthalate to obtain a solid phase polycondensation polyethylene terephthalate having an ultimate viscosity of 0.70 to 0.86 dl / g. It can solve by the manufacturing method of the polyethylene terephthalate.n n n n n n n n [However, in general formula (I), R 1 represents an alkyl group having 2 to 12 carbon atoms.] |
