| titleOfInvention | Process for production of polyethylene terephthalate |
| abstract | Disclosed is a process for production of a polyethylene terephthalate, which comprises the steps of: conducting melt polycondensation by using a compound represented by the general formula (I) as a polycondensation catalyst to yield a melt-polycondensed polyethylene terephthalate having an intrinsic viscosity ranging from 0.48 to 0.53 dL/g and the number of terminal carboxyl groups ranging from 14 to 22 mmol/kg; and subjecting the melt-polycondensed polyethylene terephthalate to solid-state polycondensation to yield a solid-state-polycondensed polyethylene terephthalate having an intrinsic viscosity ranging from 0.70 to 0.86 dL/g. (I) wherein R represents an alkyl group having 2 to 12 carbon atoms. It becomes possible to provide a polyethylene terephthalate which can be molded into an article having a reduced acetaldehyde content and a reduced oligomer content. |
