Abstract:
(EN) [Problem] To provide a wholly aromatic liquid-crystal polyester resin having exceptional heat resistance and moldability. [Solution] A wholly aromatic liquid-crystal polyester resin according to the present invention includes structural units represented by formulas (I)-(V) as essential structural units, said wholly aromatic liquid-crystal polyester resin characterized in that the compositional ratio (mol%) of the structural units (I)-(V) in the wholly aromatic liquid-crystal polyester satisfies the following conditions: 50 mol% ≤ structural unit (I) ≤ 75 mol%; 6 mol% ≤ structural unit (II) ≤ 20 mol%; 1 mol% ≤ structural unit (III) ≤ 21.5 mol%; 0.5 mol% ≤ structural unit (IV) ≤ 10.5 mol%; 2.5 mol% ≤ structural unit (V) ≤ 22 mol%; and structural unit (III) > structural unit (IV).
(FR) La présente invention concerne une résine de polyester à cristaux liquides entièrement aromatique présentant une résistance à la chaleur et une aptitude au moulage exceptionnelles. La résine de polyester à cristaux liquides entièrement aromatique de l'invention comprend des motifs de structure représentés par les formules (I) à (V) en tant qu'unités de structure essentielles, ladite résine de polyester à cristaux liquides entièrement aromatique étant caractérisée en ce que le rapport de composition (% en mole) des motifs de structure (I) à (V) dans le polyester à cristaux liquides entièrement aromatique satisfait les conditions suivantes: 50 % en mole ≤ motif de structure (I) ≤ 75 % en mole; 6 % en mole ≤ motif de structure (II) ≤ 20 % en mole; 1 % en mole ≤ motif de structure (III) ≤ 21,5 % en mole; 0,5 % en mole ≤ motif de structure (IV) ≤ 10,5 % en mole; 2,5 % en mole ≤ motif de structure (V) ≤ 22 % en mole; et motif de structure (III) > motif de structure (IV).
(JA) [課題]耐熱性および成形性に優れる全芳香族液晶ポリエステル樹脂の提供。 [解決手段] 本発明に係る全芳香族液晶ポリエステル樹脂は、 必須の構成単位として下記式(I)~(V)で表される構成単位を含んでなる全芳香族液晶ポリエステル樹脂であって、 前記全芳香族液晶ポリエステル中における構成単位(I)~(V)の組成比(モル%)が、下記の条件: 50モル%≦構成単位(I)≦75モル% 6モル%≦構成単位(II)≦20モル% 1モル%≦構成単位(III)≦21.5モル% 0.5モル%≦構成単位(IV)≦10.5モル% 2.5モル%≦構成単位(V)≦22モル% 構成単位(III)>構成単位(IV) を満たすことを特徴とする。
