<p>PROBLEM TO BE SOLVED: To obtain a flame-retardant synthetic resin composition having good physical properties and excellent in flame retardance. SOLUTION: This flame-retardant synthetic resin composition contains (A) a synthetic resin in an amount of 100 pts.wt., (B) 0.5-30 pts.wt. of a phosphoric acid ester-based flame retardant expressed by formula (1) [R1 , R2 , R4 , and R5 are each a 1-10C alkyl or an aromatic group expressed by formula (2) (A1 and A2 are each H, hydroxy, a halogen or a 1-10C alkyl), and are same or different from each other; R3 is a divalent aromatic group expressed by formula (3) (A3 and A4 are each H, a 1-4C alkyl, a cycloalkyl, an aryl, an akloxy, nitro, a halogen or cyano) or formula (4) (A5 , A6 , A7 and A8 are each H, a 1-4C alkyl, a cycloalkyl, an aryl, an alkoxy, nitro, a halogen ore cyano; B is a direct bond, bivalent S, sulfone, a 1-5C alkylidene or an alkylene); and (n) is 0-10], and (c) 0.1-5 pts.wt. zirconium oxide having an average particle diameter of <=10μm.</p> |
