Abstract

본 발명은 디메틸렌테레프탈레이트와 1,4-싸이클로헥산디메탄올, 그리고 에틸렌글리콜을 사용하여 랜덤공중합 폴리에스테르를 제조함에 있어서, 에스테르교환반응 촉매로써 망간아세테이트와 코발트아세테이트를 금속원소를 기준으로 최종합성되는 폴리머에 대하여 각각20∼70ppm 징크아세테이트, 소듐아세테이트, 포타슘아세테이트 및 마그네슘아세테이트 중 2종이상을 금속원소를 기준으로 최종 합성되는 폴리머에 대하여 각각 0.1∼2ppm으로 사용하고, 중축합촉매로써 금속원소를 기준으로 최종합성되는 폴리머에 대하여 티타늄테트라이소프로폭사이드 또는 티타늄테트라부톡사이드를 10∼60ppm, 안티모니트리옥사이드를 10∼30ppm로 각각 사용하며, 열안정제로써 다음구조식(Ⅰ)의 3.5-디-터셔리부틸-4-히드록시 벤질포스포닉산을 사용하므로써, 융점이 낮고 유동성 및 투명성이 우수하여 섬유 등 각종 성형품의 재료로 유용한 램덤 공중합 폴리에스테르를 제조하는 방법에 관한 것이다.In the present invention, in preparing random copolymerized polyester using dimethylene terephthalate, 1,4-cyclohexanedimethanol, and ethylene glycol, the final synthesis of manganese acetate and cobalt acetate as a transesterification catalyst based on metal elements For each polymer, two or more of 20 to 70 ppm zinc acetate, sodium acetate, potassium acetate and magnesium acetate are each used at 0.1 to 2 ppm relative to the polymer to be finally synthesized based on the metal element, and the metal element is used as the polycondensation catalyst. 10 to 60 ppm of titanium tetraisopropoxide or titanium tetrabutoxide and 10 to 30 ppm of antimony trioxide are respectively used for the final synthesized polymer as a standard, and 3.5-di- of the following structural formula (I) is used as a heat stabilizer. Melting point by using tert-butyl-4-hydroxybenzylphosphonic acid Low to the fluidity and transparency superior to a method for producing a useful random co-polyester as a material for various molded products such as fibers.
