PROBLEM TO BE SOLVED: To provide a thermoplastic polyester elastomer resin composition which is flexible, highly elastic and excellent in bending fatigue durability, and further, exhibits excellent moldability to be used for various moldings such as injection molding, extrusion molding, and blow molding, and to provide a molded product made of the same.SOLUTION: The thermoplastic polyester elastomer resin composition is obtained by melt blending 0.1-25 pts.wt. of polyolefin resin (B), and 0.1-15 pts.wt. of glycidyl group modified polyolefin resin (C), as well as 0.01-5.0 pts.wt. of crystal nucleating agent (D), with on 100 pts.wt. of thermoplastic polyester elastomer (A), wherein the melt flow rate is 0.5 g/10 minutes or more and 10 g/10 minutes or less, as measured with 2,160 g of loads, at the temperature To (degree C) defined by the formula (1) To=R+20 (wherein, Tm is the melting point of thermoplastic polyester elastomer (A), and Ris defined as a value obtained by rounding off Tm to the nearest 10), in accordance with ASTM D-1238. |
