Zusammenfassung:	PURPOSE:To obtain flame-retardant polyester resin composition excellent in resistance to moist heat and moldability by blending a poly(butylene naphthalate) with a specific resin in a given proportion. CONSTITUTION:The composition comprises 30-99.5wt.% poly(butylene naphthalate), preferably poly(butylene 2,6-naphthalate), 0.5-30wt.% halogenated acrylic resin obtained by polymerizing a halogenated benzyl (meth)acrylate represented by the formula (wherein X is a halogen, n is 1-5, and Z is H or CH3), up to 15wt.% flame retardant aid consisting of Sb2O3 and/or xNa2 O.Sb2O5.yH2O (wherein x is 0-1 and y is 0-4), and up to 50wt.% inorganic filler (e.g. glass fibers), the latter two being optional.
