PROBLEM TO BE SOLVED: To obtain the subject composition capable of providing high flame retardance, developing excellent mechanical characteristics, impact resistance, fluidity, or the like, by a mixing a thermoplastic resin with an aromatic phosphate and a specific phosphorus compound. SOLUTION: This composition comprises (A) 100 pts.wt. of a thermoplastic resin (preferably a polystyrene-based resin, a modified polyphenylene oxide resin, a polyester resin, or the like), (B) 1-30 pts.wt. of an aromatic phosphate of formula I [X is a group of formula II (R1 to R4 are each H or a 1-5C alkyl) or the like; Ar1 to Ar4 are each phenyl or the like; (k) and (m) are each 0-2 and k+n is 0-2] and (C) 0.1-5 wt.% of a phosphorus compound of formula III (R9 to R10 are each an alkyl, an aryl, an alkoxy or the like) (preferably, a phosphorus compound of formula IV). Preferably, the composition is further mixed with a radical generator and a phenol-based resin. Consequently, a molding product of an arbitrary shape having excellent flame retardance, mechanical characteristics, heat resistance, moldability, processability, or the like, can be provided.
