ABSTRACT:
A novel polyether having the following general formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each stand for hydrogen, an alkyl group having 1 to 20 carbon atoms or an alkenyl group having 1 to 20 carbon atoms with the exception that R.sub.1, R.sub.2 and R.sub.3 cannot stand for hydrogen at the same time, and m and n each represent an integer of 1 to 9. The polyether can capture cations when contacted with a cation-containing aqueous alkaline liquid and can release the cations to an aqueous acidic liquid, and thus serves as a cation carrier.
