    Abstract: PROBLEM TO BE SOLVED: To obtain a fiber reinforced liquid-crystal polyester composition excellent in heat resistance, flowability, dimensional stability and resistance to soldering heat by blending a specified liquid-crystal polyester resin with glass fibers. SOLUTION: This composition consists of 50-20wt.% liquid-crystal polyester consisting of structural units of formula I [wherein X stands for at least one group selected from those of formula II; two carbonyl groups of structural units (IV) are at the p- or m-position to each other, wherein at least 50mol% of the carbonyl groups are at the p-positions; and the total of structural units (II) and (III) is substantially equimolar to the structural units (IV)[, having a heat distortion temperature of 190 deg.C or higher and a liquid-crystal initiation temperature of 330 deg.C or lower and forming an anisotropic melt phase with a melt viscosity of 10,000P or lower, and 50-80wt.% glass fibers. This composition is useful for a molded article of which resistance to soldering heat is required.
