摘要： The present invention relates to a thermoplastic polyether ester elastomer (TPEE) having a hard segment and a soft segment and a method for preparing the same and, more specifically, to a thermoplastic polyether ester elastomer and a method for preparing the same, wherein a unit derived from an anhydrosugar alcohol derivative with improved reactivity derived from biomass is contained in the soft segment, and thus through the adjustment of the content of the anhydrosugar alcohol derivative, elastic characteristics and physical characteristics (for example, hardness, etc.), which are important characteristics of an elastomer, can be favorably maintained, the melting point variously required in the molding process of a final product can be easily controlled, a problem of depletion of, especially, petroleum resources as finite resources, can be solved, and environmental friendliness can be improved.
