| titleOfInvention | Process for producing polyethylene naphthalate |
| abstract | The present invention relates to a manufacturing method of a copolyester containing ethylene naphthalate unit (EN) and its application. The present invention discloses a manufacturing method of using 2,6-naphthalenedicarboxylic acid (NDA), purified terephthalic acid (PTA), and ethylene glycol (EG) to proceed with esterification reaction or using dimethyl 2,6-naphthalenedicarboxylate (NDC), dimethyl terephthalate (DMT), EG, and transesterification catalyst to proceed with transesterification reaction or using the PTA process. While the esterification reaction reaches 85 to 98 percent of esterification ratio, NDC, EG, and transesterification catalyst are added to proceed with transesterification reaction. The monomer obtained from each of previous process is added with polymerization catalyst thereafter to proceed with polycondensation reaction to produce copolyester. The produced copolyester is further polymerized at solid state to increase its viscosity. Then, the copolyester is ejected to be blow-molded so as to produce the one-way bottle which can be pasteurization. |
