Abstract: To improve the solubility of halogenated polymeric flame-retarding agents in polyesters and thereby to compensate a deterioration of the mechanical properties of the flame-retarding polyester composition, at least one phosphite compound selected from the group consisting of the compounds represented by the general formula (I) and (II), wherein R represents an alkyl group having 6 to 20 carbon atoms, R min represents hydrogen or an alkyl group having 1 to 6 carbon atoms, n is an integer of 2 to 4 and B represents alkylene having 1 to 6 carbon atoms, ether, carbonyl, thioether or sulfone group is incorporated in such flame-retarding polyester compositions.
