Abstract
Provided is a thermoplastic polyester elastomer resin composition, a method of preparing the polyester elastomer resin composition, and a molded article including the polyester elastomer resin composition. The thermoplastic polyester elastomer resin composition includes 89 to 96 wt % of a thermoplastic polyester elastomer resin (A); 1.5 to 5.5 wt % of a glycidyl group-modified olefin-based rubber polymer (B); and 1.5 to 5.5 wt % of an ionomer resin (C). The thermoplastic polyester elastomer resin composition has excellent mechanical properties and moldability; is capable of suppressing occurrence of flow marks on the inner surface of a molded article; and thus is applicable to a constant velocity joint boot.
