が好ましい。Polyester as used in the present invention means a polymer that can be obtained by polycondensation of aromatic dicarboxylic acid and/or aromatic oxycarboxylic acid and diol. Typical examples of such polyesters include polyethylene terephthalate, polybutylene terephthalate, hexamethylene terephthalate, polyethylene naphthalene dicarboxylate, polybutylene naphthalene dicarboxylate, polyhexamethylene naphthalene dicarboxylate, and polyhexamethylene-4,4'- Examples include homopolymers or copolymers such as diphenyldicarboxylate. From an industrial standpoint, polyethylene terephthalate, polybutylene terephthalate, and polymer blends of both are particularly preferred.

Brominated polystyrene having a weight average molecular weight of 100,000 to 1,000,000 is preferably used here. Of course, brominated polystyrene of relatively low weight average molecular weight, for example about 5,000, can also be used.

し樹脂組成物を溶融したときの流動性が改善されない。In addition, the general formula (I> can also contain other vinyl compounds [wherein P is an integer of 1 to 4]) by brominating commercially available dioctyl phthalate.
Manufactured by Brominated polystyrene and brominated dioctyl phthalate may be produced separately and then mixed to form a composition within the range of the present composition, or polystyrene and dioctyl phthalate may be mixed and then both may be brominated simultaneously. In the blending ratio, the weight ratio of brominated dioctyl phthalate/brominated polystyrene is 3 to 40/9
7-60, preferably 4-25/96-75, more preferably 5-20/95-80. If the amount of brominated dioctyl phthalate is too less than the above ratio, the fluidity of the resin composition will not be improved when it is melted during molding.

ましい配合ではない。The flame retardant resin composition of the present invention can be easily made flame retardant by using an inorganic flame retardant aid. Examples include antimony compounds such as antimony trioxide, antimony pentoxide, and sodium antimonate, boron compounds such as barium metaborate and zinc borate, zirconium compounds, and molybdenum compounds. Among these, antimony compounds are preferably used. A flame retardant aid may be used without coating the surface with a thermosetting resin or silicone resin. When this inorganic flame retardant aid is used in combination, the amount added is preferably 0.5 to 20% by weight, more preferably 1 to 10% by weight, based on the total composition. If it is less than 0.5% by weight, the flame retardant effect will not be sufficient, and if it exceeds 20% by weight, the properties of the composition as a molded article, such as mechanical strength, will be significantly reduced, which is not a preferable blend.
