    Abstract: The invention relates to block copolymer comprising i) A first block wherein at least 65 mol-% of the repeating units of the first block are repeating units of the formula (I)—[CH2—CH2—O]—, ii) A second block wherein at least 90 mol-% of the repeating units of the second block are repeating units of at least one of formulae (II) or (III), wherein the groups R1, R2, and R3 independent of each occurrence are selected from hydrocarbyl groups having 1 to 40 carbon atoms, which are optionally substituted by ether or hydroxyl groups, and wherein the groups R1 and R2 are optionally linked to each other such that a nitrogen heterocyclic structure is present, iii) A third block which is different from the first block and the second block and which is more hydrophobic than the first block.

    Abstract: A method of production of a polyether rubber containing unit expressed by the following general formula (1) in 0.1 mol % or more and less than 30 mol % obtained by reacting a polyether rubber containing epihalohydrin monomer unit in 0.1 mol % or more and a nitrogen atom-containing aromatic heterocyclic compound by kneading in the presence of an acid acceptor containing at least a hydrotalcite having a nitrogen adsorption specific surface area as measured by a BET method of 10 m2/g or more is provided. wherein, in the above general formula (1), A+ is a group containing a cationic nitrogen-containing aromatic heterocyclic ring, and is bonded with a carbon atom at the “2” position shown in the above general formula (1) through a nitrogen atom constituting the cationic nitrogen-containing aromatic heterocyclic ring, and X− is any counter anion.
