A flame retarded polyolefin resin composition comprises polyolefin resin, 1 to 40 parts by weight per 100 parts of the polyolefin resin of a brominated bisphenol ether derivative of the formula:
wherein R is hydrogen or methyl, and A is ―C(CH3)2―, ―SO2―, ―S―, or ―CH2― ; and 1 to 30 parts by weight per 100 parts of the polyolefin resin of 2,4,6-tris(mono-, di- or tribromophenoxy)triazine.
Herein is disclosed a flame-retarded thermoplastic resin composition which comprises an original flame-retarded thermoplastic resin composition comprising certain amounts of a thermoplastic resin and of a brominated flame-retardant, and, in combination therewith, a certain amount of a dolomite compound, or in addition thereto, a certain amount of at least one compound selected from a hydrotalcite, a zinc-substituted hydrotalcite compound, or a zeolite compound, which flame-retarded thermoplastic resin composition of the present invention are remarkably improved in heat stabilizing effects as compared with the original flame-retarded thermoplastic resin composition.
