| description | The present invention relates to a method for preparing a wholly aromatic polyester resin with high heat resistance and flowability which is necessary for producing engineering plastics suitable for electric and electronic components, and wholly aromatic polyester prepared by the method. The method for preparing a wholly aromatic polyester resin can prepare the wholly aromatic polyester resin with excellent high temperature heat resistance and molding flowability, by controlling a usage content of refracted main-chain forming monomers containing p-hydroxybenzoic acid among material monomers used in preparing the wholly aromatic polyester resin, into a specific molar ratio with a usage content of hard linear structure forming monomers.
본 발명은 전기전자 부품용에 적합한 엔지니어링 플라스틱을 제조하기 위해 필요한 고내열성 및 고유동성을 갖는 유동성이 향상된 전방향족 폴리에스테르 수지의 제조방법 및 이에 따라 제조된 전방향족 폴리에스테르에 관한 것이다. 본 발명에 따른 전방향족 폴리에스테르 수지의 제조방법은 전방향족 폴리에스테르 수지의 제조과정에서 사용하는 원료 단량체 중 파라 히드록시 벤조산을 포함하는 굴절 주쇄 형성 단량체의 사용함량을 경질 선형 구조 형성 단량체의 사용함량과의 특정 몰비로 조절함으로써 고온 내열성도 우수할뿐만 아니라 성형 유동성도 우수한 전방향족 폴리에스테르 수지를 제조할 수 있다. |
