Claims (1)

주된 반복구조단위가 에틸렌테레프탈레이트인 폴리에스터를 제조함에 있어서, 중합반응이 완결되기 이전의 임의의 단계에서 하이드로퀴논 또는 에스테르 형성성 유도체를 폴리에스터를 구성하는 산 성분에 대하여 0.2-0.2몰% 첨가하여 반응시키는 것을 특징으로 하는 폴리에스터의 제조방법.In preparing a polyester whose main repeating unit is ethylene terephthalate, add 0.2-0.2 mol% of the hydroquinone or ester-forming derivative to the acid component constituting the polyester at any stage before the polymerization is completed. Method for producing a polyester, characterized in that the reaction. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
