ABSTRACT:
The present invention provides a liquid crystal polyester resin composition, which is manufactured at low cost and has favorable gas barrier properties and improved impact resistance, vibration-damping properties, thin-wall properties (mechanical properties of thin-wall molded articles), and film-forming properties, while maintaining excellent heat resistance and mechanical properties of a liquid crystal polyester. The liquid crystal polyester resin composition of the invention includes 55.0 through 99.9 percent by weight of a liquid crystal polyester as a component (A), and 0.1 through 45.0 percent by weight of an epoxy group-containing ethylene copolymer as a component (B), wherein the component (B) includes: (a) 50 through 96.5 percent by weight of an ethylene unit; (b) 0.5 through 30 percent by weight of an unsaturated glycidyl carboxylate unit or an unsaturated glycidyl ether unit; and (c) 3 through 40 percent by weight of an ethylenically unsaturated ester compound unit.
