Abstract

본 발명은 고점도 폴리에스테의 제조방법에 관한 것으로, 적어도 한 종류의 이관능성 산 또는 그의 알킬에스테르 유도체와 적어도 한종류의 디올을 촉매 존재하에 에스테르화 반응 및 축중합 반응시켜 폴리에스테르를 제조하는 방법에 있어서, 상기의 에스테르화 반응 촉매와 축중합 반응 촉매의 투입량이 다음 식을 만족시키도록 조절된 폴리에스테르의 제조방법에 의하면, 양 촉매의 투입량을 조절하여 극한 점도의 상승속도를 제어함으로써 기포 발생량이 현저하게 저하되고 색상이 양호한 고점도의 폴리에스테르를 높은 수율로 제조할 수 있다.The present invention relates to a method for producing a high-viscosity polyester, to a method for producing a polyester by esterification and polycondensation reaction of at least one difunctional acid or alkyl ester derivative thereof and at least one diol in the presence of a catalyst. In the polyester production method in which the amount of the esterification catalyst and the polycondensation catalyst is adjusted to satisfy the following equation, the amount of bubble generation is controlled by controlling the rate of increase of the intrinsic viscosity by adjusting the amount of the catalyst input. High viscosity polyesters with markedly lowered color and good color can be produced in high yields.

A : 에스테르화 반응 촉매 투입량(mmol%)A: Amount of esterification catalyst (mmol%)

B : 축중합 반응 촉매 투입량(mmol%)B: amount of polycondensation reaction catalyst (mmol%)
