Abstract

A wholly aromatic liquid crystalline polyester resin composition comprising about 97-60 parts by weight of a wholly aromatic polyester resin (A) having melting peak determined by DSC equal to or higher than 310° C.; and about 3-40 parts by weight of a wholly aromatic polyester resin (B) having melting peak determined by DSC equal to or lower than 300° C. is provided. The novel liquid crystalline polyester resin composition of the present invention exhibits an improved melt flowability and can provide a molded article having reflow-soldering heat resistance.
