FLAME-RETARDANT LIQUID CRYSTAL POLYESTER RESIN COMPOSITION

PROBLEM TO BE SOLVED: To provide a flame-retardant liquid crystal polyester resin composition capable of forming a molded article having good flame-retardancy even in the form of an extremely thin molding, wherein a residence stability in flow for a molding process is improved and an expansion of a molding due to gases is suppressed to give superior color tons to the molding. SOLUTION: The flame-retardant liquid crystal polyester composition comprises: (A) 100 pts.wt. of a liquid crystal polyester; (B) 5 to 200 pts.wt. of a filler; (C) 0.5 to 100 pts.wt. of a styrene resin; and (D) 0.2 to 5 pts.wt. of a phosphoric acid ester represented by the following formula (1). Furthermore, the weight proportion of the phosphoric acid ester (D) to styrenic resin (C), (D)/(C), is 15/85 to 50/50, and still further, the weight proportion of the sum of the styrenic resin (C) and the phosphoric acid ester (D) to the liquid crystal polyester resin (A) (C)+(D)}/(A) is in the range of 1/99 to 10/90.
