    摘要: Disclosed is a polyester composition obtained by blending, with a polyester comprising at least 80% by mole of ethylene terephthalate units, (1) an epoxy compound (A) having an isocyanuric acid ester construction or a cyanuric acid ester construction and at least one organic compound (B) capable of reacting with the epoxy group of said epoxy compound (A) and having one or more carboxyl, amino, isocyanate or hydroxyl groups or (2) a product of a melt reaction of said epoxy compound (A) with said organic compound (B), and then melt mixing and milling the blend. The polyester composition may comprise a fibrous filler and glass flakes, and has a high moldability and excellent physical properties.
