METHOD FOR PREPARING WHOLLY AROMATIC POLYESTER RESIN AND WHOLLY AROMATIC POLYESTER RESIN PREPARED BY THE METHOD
본 발명은 양산 스케일 중축합 반응에 의한 전방향족 폴리에스테르 수지의 제조 공정에서, 중축합 반응에 참여하지 못한 모노머 및 아세틸화된 모노머가 고온에서 초산 가스와 함께 유출되는 것을 최소화하여 초기 투입된 원료 모노머의 몰비를 유지시켜 중축합 반응을 수행함으로써 최종 제조되는 전방향족 폴리에스테르 수지의 물성을 동등하게 할 수 있는, 전방향족 폴리에스테르 수지의 제조 방법에 관한 것이다. 또한, 본 발명에 따라 제조된 전방향족 폴리에스테르 수지는 목적한 물성이 배치별 동등하게 발현되어 이를 성형하여 제조되는 자동차 부품, 전기...

| description | 본 발명은 양산 스케일 중축합 반응에 의한 전방향족 폴리에스테르 수지의 제조 공정에서, 중축합 반응에 참여하지 못한 모노머 및 아세틸화된 모노머가 고온에서 초산 가스와 함께 유출되는 것을 최소화하여 초기 투입된 원료 모노머의 몰비를 유지시켜 중축합 반응을 수행함으로써 최종 제조되는 전방향족 폴리에스테르 수지의 물성을 동등하게 할 수 있는, 전방향족 폴리에스테르 수지의 제조 방법에 관한 것이다. 또한, 본 발명에 따라 제조된 전방향족 폴리에스테르 수지는 목적한 물성이 배치별 동등하게 발현되어 이를 성형하여 제조되는 자동차 부품, 전기·전자부품, 소형·정밀 성형품 등의 신뢰성을 높일 수 있다.
The present invention relates to a method for preparing a wholly aromatic polyester resin, wherein, in the preparation process of a wholly aromatic polyester resin by a mass-production scale polycondensation reaction, a polycondensation reaction is carried out such that the molar ratio of initially fed raw monomers is maintained by minimizing the outflow of the monomers and the acetylated monomers, which does not participate in the polycondensation reaction, together with acetic acid gas at a high temperature, and thus, the physical properties of the finally prepared wholly aromatic polyester resin can be equalized. In addition, the wholly aromatic polyester resin prepared according to the present invention has desired physical properties, which are equally expressed for respective batches, and thus, can improve the reliability of automobile parts, electric and electronic parts, small-sized precision molded articles, and the like, which are manufactured by molding the wholly aromatic polyester resin. |
