    摘要: The present invention relates to a thermoplastic polyester elastomer composition, a method of preparing the same, and a molded article including the same. More particularly, the present invention relates to a thermoplastic polyester elastomer composition including 100 parts by weight of a thermoplastic polyester elastomer (A); 0.5 to 2.5 parts by weight of a glycidyl group-modified olefin-based rubber polymer (B) containing 10 to 17 % by weight of glycidyl (meth)acrylate; and 0.67 to 1.45 parts by weight of a carbodiimide-based compound (C), a method of preparing the thermoplastic polyester elastomer composition, and a molded article including the thermoplastic polyester elastomer composition.
    According to the present invention, the present invention has an effect of providing a thermoplastic polyester elastomer composition having excellent fluidity, hardness, tensile strength, tensile elongation, heat aging resistance, and grease resistance and satisfying weight reduction, miniaturization, and aesthetics required in the automotive and electrical/electronic fields, a method of preparing the thermoplastic polyester elastomer composition, and a molded article including the thermoplastic polyester elastomer composition.
