PURPOSE: A thermoplastic polyether ester elastomer resin composition is provided to improve thermal stability and weather resistance and to ensure the application to the fields exposed to the external environment of high temperature and ultraviolet lights due to improved thermal stability and weather resistance. CONSTITUTION: A thermoplastic polyether ester elastomer resin composition comprises polyesterether block copolymers, alkali metal salts of organic acids, amine-based heat-resistant agents, ultraviolet-absorbing agents and radical scavengers. The polyesterether block copolymer has the surface hardness of shore 25D - 82D. The polyesterether block copolymer comprises the hard segment represented by chemical formula 1 and the soft segment represented by chemical formula 2. The ultraviolet-absorbing agent comprises one kind or more selected from the group consisting of a benzotriazole-based compound and a benzophenone-based compound. |
