| titleOfInvention | Wholly aromatic liquid crystal polyester resins, molded articles, and electrical and electronic components |
| abstract | The present invention provides a wholly aromatic liquid crystal polyester resin having a particularly low dielectric loss tangent and excellent heat resistance. The wholly aromatic liquid crystal polyester resin of the present invention is characterized in that it contains a structural unit (I) derived from 6-hydroxy-2-naphthoic acid, a structural unit (II) derived from an aromatic diol compound, and a structural unit (III) derived from an aromatic dicarboxylic acid compound, wherein the structural unit (III) includes a structural unit (IIIA) derived from terephthalic acid and 2,6-naphthalene-derived At least one of the structural unit (IIIB) derived from dicarboxylic acid and the structural unit (IIIC) derived from isophthalic acid, the composition ratio (mol %) of the structural unit satisfies the following condition: 40 mol %≤constitutive Unit (I)≤80mol%, 10mol%≤Structural unit (II)≤30mol%, 3mol%≤Structural unit (IIIA)≤28mol%, 0mol%≤Structural unit (IIIB)≤9mol% , 0 mol% ≤ structural unit (IIIC) < 5 mol % (wherein, structural unit (IIIB) and structural unit (IIIC) are not both 0 mol %.). |
