Flame retardant reinforced with thermoplastic polyester resin compositions are disclosed glass fiber and a system of flame retardants represented by the following general formulas (I) and (II), together with antimony trioxide. The flame retardant system is a blend of 1-20 parts by weight of component (I), and 2-40 parts by weight of component (II), provided the weight ratio (I)/(II) of the flame retardant components (I) to (II) is in the range of 0<(I)/(II)</=5, and that the total amount of flame retardants (I) plus (II) is in the range of 3-40 parts by weight. From 2 to 3 parts by weight of antimony trioxide is present and 5 to 60% by weight of glass fiber is also present, these two percentages being expressed on the basis of the weight of the total resin composition. The resin compositions exhibit outstanding mechanical, thermal, forming and machining properties in addition to being fire retardant. <IMAGE> [I] <IMAGE> <IMAGE> [II] <IMAGE> in which X is hydrogen, chlorine or bromine, the average value for l and m are independently 0 to 11 and the halogen content is 10% or more by weight. Values for R1 and R2 are given in the attached specification.
