摘要：
A method for demineralizing water or an aqueous solution, which comprises contacting the water or the aqueous solution to be treated to a strongly basic anion exchanger made of a crosslinked polymer having a constituting unit of the following formula (I):
wherein A is a C 1-2 linear alkylene group B is a C 4-8 linear alkylene group, each of R1, R2 and R3 which may be the same or different, is a C 1-4 alkyl group or a C 2-4 alkanol group, X is a counter ion coordinated on the ammonium group, and the benzene ring D may have an alkyl group or a halogen atom as a substituent.
