Document Type and Number:
WIPO Patent Application WO/2022/004630
Kind Code:
A1
Abstract:
[Problem] To provide a resin composition with which there is obtained a resin molded article having a low dielectric loss tangent and exceptional mechanical strength such as toughness, etc. [Solution] The resin composition according to the present invention includes a liquid crystal polyester resin (A) and a filler (B), wherein: the liquid crystal polyester resin (A) includes 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; the structural unit (III) includes a structural unit (IIIA) derived from terephthalic acid and/or a structural unit (IIIB) derived from 2,6-naphthalenedicarboxylic acid; the compositional ratio of the above structural units (mol%) satisfies the conditions that 40 mol%≤structural unit (I)≤75 mol%, 12 mol%≤structural unit (II)≤30 mol%, and 12 mol%≤structural unit (III)≤30 mol%; the filler (B) is at least one selected from the group consisting of silica, mica, and talc; and the resin composition is characterized by having a dielectric loss tangent measured by the cavity resonator perturbation method at a measurement frequency of 10 GHz of 1.0×10-3 or less.
