The present invention relates to a thermoplastic polyether ester elastomer (TPEE) having a hard segment and a soft segment, and a method for preparing same. More specifically, the present invention relates to a TPEE comprising, within a hard segment and a soft segment, units derived from a furandicarboxylic compound or from a combination of a furandicarboxylic compound and an aromatic dicarboxylic compound, and in the soft segment, units derived from biomass-derived anhydrous sugar alcohol derivatives having improved reactivity, and to a method for preparing the TPEE. The present invention enables more convenient control over the melting point, which is required to vary in the forming process for end products, while maintaining desirable elastic properties and physical properties (for example, hardness and thermal degradation temperature), which are important properties for an elastomer, can address the issue of the exhaustion of petroleum, which is a non-renewable resource, and can further ...
