알킬렌테레프탈레이트를 주성분으로 하는 폴리에스텔을 얻기 위하여 중축합 반응을 행할때 아래 일반식When the polycondensation reaction is carried out to obtain a polyester containing alkylene terephthalate as a main component, (단, M은 알칼리금속 또는 암모늄염을 표시하고, x,y는 0 내지 5의 정수이며 R은 탄소수 1 내지 5의 알킬기, 치환기를 갖거나 또는 가지지 않는 아릴기, 싸이클로알킬기, 또는 할로알킬, 할로아릴, 할로싸이클로 알킬기를 표시하며, 여기서 치환기로는 각종 알킬기, 금속설포네이트기, 아민기등을 들 수 있다)을 가진 옥시알킬렌 글리콜포스페이트 화합물을 상기 중축합 반응과정 중에서 투입하여 최종 폴리머에서의 인 원자의 함량이 0.4 내지 1.5중량 %가 되도록 하는 것을 특징으로 하는 난연성 폴리에스텔의 제조방법.(Wherein M represents an alkali metal or ammonium salt, x, y is an integer of 0 to 5 and R is an alkyl group having 1 to 5 carbon atoms, an aryl group having no or no substituent, a cycloalkyl group, or haloalkyl, halo) Aryl and halocycle are alkyl groups, and as substituents, oxyalkylene glycol phosphate compounds having various alkyl groups, metal sulfonate groups, amine groups, etc.) may be added during the polycondensation reaction to produce the final polymer. A method for producing a flame retardant polyester, characterized in that the content of the phosphorus atom is 0.4 to 1.5% by weight. 제 1 항에서 일반식(1)의 옥시알킬렌 글리콜의 반복수 x,y가 0 내지 5의 정수이며 적어도 하나의 x 또는 y는 0이 아닌것을 만족하는 난연성 폴리에스텔의 제조방법.The method for producing a flame retardant polyester according to claim 1, wherein the number of repetitions x, y of the oxyalkylene glycol of the general formula (1) is an integer of 0 to 5 and at least one of x or y is not zero. 제 1 항에 있어서, 일반식(1)의 화합물을 상기 폴리에스텔을 얻기 위한 중축합 반응 과정중 폴리머의 극한 점도가 0.3이상되는 시점에서 투입하는 난연성 폴리에스텔의 제조방법.The method for producing a flame retardant polyester according to claim 1, wherein the compound of the general formula (1) is added at a time when the intrinsic viscosity of the polymer is 0.3 or more during the polycondensation reaction to obtain the polyester. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
