Abstract

본 발명은 색조 및 투명성이 우수하며 압출 중공성형이 가능한 폴리에스테르 공중합체의 제조방법에 관한 방향족 디카르본산 50∼100몰%와 지방족 디카르본산 0∼50몰%로 구성되는 디카르본산과 방향족 디올 0∼50몰%와 에틸렌글리콜 100∼50몰%로 구성되는 디올을 반응시켜 폴리에스테르 공중합체를 제조하되 에스테르 교환 반응 및 중축합 반응시 촉매, 안정제 및 색조개선재를 첨가하고 지방족 사슬을 도입하며 제조된 중합체를 불활성 개스 또는 고진공하 190∼230℃온도에서 고상 중합을 행하여 고유점도가 0.09∼1.20dlg인 압출 중공성형용 폴리에스테르 공중합체의 제조방법에 관한 것이다.The present invention relates to a dicarboxylic acid and an aromatic composition comprising 50 to 100 mol% of aromatic dicarboxylic acid and 0 to 50 mol% of aliphatic dicarboxylic acid in a method for producing a polyester copolymer having excellent color tone and transparency and capable of extrusion blow molding. To prepare a polyester copolymer by reacting a diol composed of 0 to 50 mol% of diol and 100 to 50 mol% of ethylene glycol, add a catalyst, stabilizer and color tone improver and introduce aliphatic chain during transesterification and polycondensation reaction. The present invention relates to a method for producing an extruded blow molding polyester copolymer having an intrinsic viscosity of 0.09 to 1.20 dlg by subjecting the prepared polymer to solid phase polymerization at an inert gas or at a high vacuum at 190 to 230 ° C.
