    • The present invention provides a wholly aromatic liquid-crystalline polyester consisting of the repeating units represented by formulae (I), (II), (III) and (IV): wherein: the molar proportion of the repeating unit represented by formula (I) based on the total repeating units constituting the wholly aromatic liquid-crystalline polyester is 40-80 mol %; the molar ratio of the total amount of the repeating units represented by formulae (II) and (III) to the repeating unit represented by formula (IV) is from 90/100 to 100/90; the molar proportion of the repeating unit represented by formula (II) based on the total amount of the repeating units represented by formulae (II) and (III) is 80-99.9 mol%; and the two “—O—” attached to the benzene ring in formula (III) are positioned meta or para to each other and “Ar” in formula (IV) represents a bivalent aromatic group. The wholly aromatic liquid-crystalline polyester of the present invention exhibits excellent dielectric properties in high frequency regions as well as good mechanical properties such as impact strength.
    • 本发明提供由式(I),(II),(III)和(IV)表示的重复单元组成的全芳族液晶聚酯:其中:由式(I)表示的重复单元的摩尔比例 基于构成全芳香族液晶聚酯的总重复单元为40〜80摩尔%。 由式(II)和(III)表示的重复单元的总量与由式(IV)表示的重复单元的摩尔比为90/100〜100/90; 由式(II)表示的重复单元相对于式(II)和(III)表示的重复单元的总量的摩尔比例为80-99.9摩尔% 并且与式(III)中的苯环相连的两个“-O-”彼此定位为间位或对位,式(IV)中的“Ar”表示二价芳基。 本发明的全芳香族液晶聚酯在高频区域表现出优异的介电性能以及良好的机械性能如冲击强度。
