Abstract
The present invention is aimed to provide polyether polymers capable of improving an ion conductivity around room temperature as well as ion conductible polymer compositions and electrochemical devices using the same. The above objectives are achieved by using polyether polymers characterized by having the structure unit represented by the formula (1) and the structure unit represented by the formula (2) and/or the structure unit represented by the formula (3), and having polymerizable and/or non-polymerizable functional groups at each end of the molecular chains.
