Abstract

본 발명은 하기 구조식(I)로 표현되는 단위체 (I) 20~80몰%, 하기 구조식 (II)로 표현되는 단위체(II) 5~40몰%, 하기 구조식 (III)으로 표현되는 단위체 (III) 5~40몰% 및 하기 구조식 (IV)로 표현되는 단위체 (IV) 5~40몰%를 중합하되 단위체 (I)의 화합물을 중합의 단계적 혹은 연속적 승온과정중에 다단계로 투입, 더욱 바람직하기로는 초기 중합시 단위체 (I)의 화합물을 전체 단위체 (I)에 대하여 30~70%를 투입하고 280~300℃의 중합온도 범위내에서 단위체 (I)의 잔여량을 투입하므로써 방향족 폴리에스테르의 블럭화를 최대한 억제시킨 분해온도 이하에서의 용융가공성 및 기계적 물성이 우수한 방향족 폴리에스테르의 제조방법에 관한 것이다.The present invention is 20 to 80 mol% of a unit (I) represented by the following structural formula (I), 5 to 40 mol% of a unit (II) represented by the following structural formula (II), a unit represented by the following structural formula (III) 5 to 40 mol% and 5 to 40 mol% of the unit (IV) represented by the following structural formula (IV) are polymerized, but the compound of the unit (I) is added in multiple stages during the stepwise or continuous temperature raising process of the polymerization. In the initial polymerization, 30 to 70% of the compound of the unit (I) is added to the entire unit (I), and the remaining amount of the unit (I) is added within the polymerization temperature range of 280 to 300 ° C to maximize the blocking of the aromatic polyester. The present invention relates to a method for producing an aromatic polyester having excellent melt processability and mechanical properties below the suppressed decomposition temperature.
