Flame-retardant polyester resin compositions are disclosed which have improved mechanical properties, particularly improved impact properties. The compositions comprise a halogen-containing copolymeric polyester resin derived from terephthalic acid or its derivative, an alkylene glycol or its derivative and a halogen-containing aromatic diol, said copolymeric polyester resin being blended with a minor amount of a modified ethylene copolymer derived by graft polymerization of an alpha , beta -unsaturated carboxylic acid or its derivative on the backbone of ethylene/ alpha -olefin copolymer, and/or a minor amount of an acrylic rubber. |
