Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystalline resin composition having little variance of electroconductivity in a region ranging from a semiconductive one to a high conductive one, having high fluidity and excellent in appearance of a molded product, a liquid crystalline resin master batch and a liquid crystalline resin molded product composed thereof. SOLUTION: The liquid crystalline resin composition comprises 100 pts.wt. liquid crystalline resin (A) satisfying (a1) 250-350°C melting point and (a2) 1-80Pa s melt viscosity at a temperature 20°C higher than the melting point and 1000sec-1shear rate, and 0.5-40 pts.wt. gas phase carbon fiber (B) having 10-500 nm fiber major diameter and 5-1,000 aspect ratio. The molded product can be produced, e.g., by bringing the liquid crystalline resin composition to be a master batch and, if necessary, adding another thermoplastic resin (C). The molded product excellent in dispersibility and electroconductivity is obtained by bringing melt viscosities of the both to be nearly equal. COPYRIGHT: (C)2008,JPO&INPIT
