Dimethyl-2,6-naphthalene dicarboxylate, dimethyl terephthalate and the ultraviolet barrier method for manufacturing a superior polyester resin comprising ethylene glycol dimethyl 2,6-naphthalenedicarboxylate, dimethyl terephthalate and ethylene a glycol ester prepared by reacting an oligomer exchange and polycondensation of the prepared oligomer and manufacture the whole polymer (prepolymer), and a pre-prepared polymer comprising: a solid-state polycondensation for 10-20 hours. The method of the present invention provides an excellent molding that can block ultraviolet radiation of less than 36nm St. copolymer, which for food packaging containers such as easy fruit drinks or vitamin to be deteriorated by ultraviolet rays without adding a separate UV filters or colored when using It can be prepared.
