Abstract: PURPOSE:To prepare a resin molding having excellent specific strength, specific modulus, and impact strength and a low mechanical anisotropy by compounding a liq. crystalline polyester consisting of specific structural units with a high- molecular complex and a filler. CONSTITUTION:100 pts.wt. liq. crystalline polyester consisting of structural units of formulas I, II, and V and structural unit of formula III and/or structural unit of formula IV is compounded with 1-200 pts. wt. at least one high-molecular complex consisting of at least one arom. dicarboxylic acid constituting structural unit V and a divalent metal atom, and 0-150 pts.wt. filler are compounded. In formulas III and V, X represents at least one group selected from the group consisting of a group of formula VI, etc.; and Y, at least one group selected from the group consisting of a group of formula V, etc. The sum of molar amts. of structural units II, III, and IV is substantially the same as the molar amt. of structural unit V.
