Liquid-crystalline polyester resin composition and connector using the same

摘要

A liquid-crystalline polyester resin composition is provided including a liquid-crystalline polyester obtained by polymerizing monomers of an aromatic hydroxycarboxylic acid in the presence of an imidazole compound. The composition also includes a mica which is a muscovite and has a volume average particle diameter of 40 μm or less and a specific surface area of 6 m2/g or less, the amount of the mica being 15 to 100 parts by weight based on 100 parts by weight of the liquid-crystalline polyester. The liquid-crystalline polyester resin composition has melt fluidity sufficient to be molded into a connector having an ultra-thin wall thickness portion. The resulting connector has sufficiently suppressed warp and sufficient soldering resistance.
