A manufacturing method of the copolyester containing 2,6-ethylene naphthalate unit (EN) by using 2,6-naphthalenedicarboxylic acid (NDA), purified terephthalic acid (PTA), and ethylene glycol (EG) to proceed with esterification or by using dimethyl 2,6-naphthalenedicarboxylate (NDC), dimethyl terepht
A manufacturing method of the copolyester containing 2,6-ethylene naphthalate unit (EN) by using 2,6-naphthalenedicarboxylic acid (NDA), purified terephthalic acid (PTA), and ethylene glycol (EG) to proceed with esterification or by using dimethyl 2,6-naphthalenedicarboxylate (NDC), dimethyl terephthalate (DMT), EG, and transesterification catalyst to proceed with transesterification reaction or by PTA process. While the esterification reaction reaches 85_98 percent of esterification ratio, NDC, EG, and transesterification catalyst are added to proceed with transesterification reaction. The monomer obtained from previous procedure is added with polymerization catalyst thereafter to proceed with polycondensation reaction to produce copolyester of which the viscosity is increased through solid state polymerization. Then, the copolyester is ejected to be blow-molded so as to produce the one-way bottle which can meet the requirement of pasteurization.
