摘要： The present invention provides flame retardants which can provide high flame retardancy by means of silicon compounds.
A flame retardant comprising an aromatic group-containing organosiloxane compound
   wherein said compound has the following mean composition formula (1), does not flow at 23°C, flows at 200°C, does not gelate when headed at 200°C with stirring for 30 minutes, has a number average molecular weight of not less than 2,000 and at the same time, dissolves not less than 100 g in 1 L of a solvent toluene at 23°C;

        R 1   m R 2   n SiO (4-m-n)/2      (1)

in the formula, R 1 represents a univalent aliphatic hydrocarbon group containing 1 to 4 carbon atoms; R 2 represents a univalent aromatic hydrocarbon group containing 6 to 24 carbon atoms; R 1 and R 2 each may contain two or more species; and m and n are numbers satisfying 1.1 ≦ m + n ≦ 1.7 and 0.4 ≦ n/m ≦ 2.5.
