Abstract
본 발명은 파라옥시벤조일 성분과 나프토일 성분으로 이루어진 전방향족 폴리에스테르 조성물에 관한 것으로써, 다음 구조단위(I) 성분이 40-70몰%, 다음 구조단위(Ⅱ)성분과 다음 구조단위 (Ⅲ)분의 합이 20-50몰%, 다음 구조단위 (Ⅳ)성분이 10-30몰%로 이루어져 있어서, 가격이 저렴할 뿐만아니라 380℃이하의 온도에서 이방성 용융상을 나타내기 때문에 용융가공시 쉽게 배향성을 높일 수 있으며, 가공온도가 300~350℃로서 종래의 일반적인 기술에 의해 가공할 수 있어서 특히정밀전기, 전자부품의 재료로 매우 유용한 전방향족 폴리에스테르 조성물에 관한 것이다.The present invention relates to a wholly aromatic polyester composition comprising a paraoxybenzoyl component and a naphthoyl component, wherein the next structural unit (I) component is 40-70 mol%, the next structural unit (II) component and the next structural unit (III) 20-50 mol% of the total and 10-30 mol% of the following structural unit (IV) components are not only inexpensive but also show an anisotropic molten phase at temperatures below 380 ° C. Orientation property can be improved, and processing temperature is 300-350 degreeC, and it can process by a conventional general technique, and especially it is related with the wholly aromatic polyester composition which is very useful as a material of precision electric and electronic components.
