First claim
Opening claim text (preview).
The invention claiemd is: 1 . A polyether compound having a cationic group and two or more chain end groups, wherein all of the chain end groups are any of a hydroxyl group and an azide group, the polyether compound contains a linking group derived from a polyfunctional compound in the polymer main chain, and a functional group of the polyfunctional compound is at least one group selected from a group consisting of an alkynyl group, an isocyanate group and a halogenosilyl group. 2 . A gas separation membrane comprising the polyether compound according to claim 1 . 3 . The polyether compound according to claim 1 , wherein all of the chain end groups are hydroxyl groups. 4 . The polyether compound according to claim 1 , wherein all of the chain end groups are azide groups. 5 . A polyether compound according to claim 1 composed of a monomer unit represented by the following general formula (1): wherein, in the above formula (1), A+ represents a cationic group or a cationic group-containing group, X″ represents any counter anion, R represents a non-ionic group, “n” is an integer of 1 or more, and “m” is an integer of 0 or more.
