| titleOfInvention | A METHOD OF PRODUCTION OF A COPOLIESTER CONTAINING A UNIT OF ETHYLENE NAFTALATE AND ITS APPLICATION. |
| abstract | A process for producing a copolyester containing ethylene naphthalate unit, comprising the addition of 2,6-dimethyl naphthalenedicarboxylate and transesterification catalyst to the reaction mixture for direct esterification of purified terephthalic acid and ethylene glycol (PTA process ) at a stage where the esterification ratio is between 85% and 98%; and while the secondary product methyl alcohol is completely separated, subsequently adding polycondensation catalyst so that the polycondensation takes place to obtain a copolyester with an intrinsic viscosity between 0.3, 0.7 dl / g per copolymerized with the following structure of 5 ¿ 15 mole percent based on the total copolyester amount of the copolymerization |
