Claims (3)
- 알킬렌테레프탈레이트를 주성분으로 하는 폴리에스텔을 얻기 위하여 중축합 반응을 행할때 아래 일반식(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.
- 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.
- 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.
