Document Type and Number:
WIPO Patent Application WO/2023/145517
Kind Code:
A1
Abstract:
Provided are: a liquid crystalline resin composition which exhibits good fluidity and enables production of a planar connector which exhibits excellent crack resistance and mechanical strength and in which warping is suppressed; and a planar connector containing said liquid crystalline resin composition. This liquid crystalline resin composition for a planar connector contains: (A) a wholly aromatic polyester; (B) a fibrous inorganic filler; (C) mica; and (D) talc and/or silica. Component (A) contains constituent units (I) to (IV). Relative to the total amount of constituent units, the amount of (I) is 40-75 mol%, the amount of (II) is 0.5-7.5 mol%, the amount of (III) is 8.5-30 mol%, and the amount of (IV) is 8.5-30 mol%. The weight average fiber length of component (B) is 150-500 μm. Relative to the total amount of the composition, the amount of component (A) is 45-70 mass%, the amount of component (B) is 5-20 mass%, the amount of component (C) is 7-27 mass%, the amount of component (D) is 5-25 mass%, and the total amount of components (B) to (D) is 30-55 mass%. Ar1 and Ar2 each independently denote an arylene group.
