ABSTRACT:
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 compoundwherein said compound has the following mean composition formula (1), does not flow at 23° C., flows at 200° C., does not gelate when heated 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.:in-line-formulae description="In-line Formulae" end="lead"?R1mR2nSiO(4-m-n)/2  (1)in-line-formulae description="In-line Formulae" end="tail"?in the formula, R1represents a univalent aliphatic hydrocarbon group containing 1 to 4 carbon atoms; R2represents a univalent aromatic hydrocarbon group containing 6 to 24 carbon atoms; R1and R2each 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.
