Abstract:
The invention relates to a copolymer of ethylene oxide or propylene oxide and at least one substituted oxirane bearing an ionic group.The copolymer is characterized in that its chain comprises repeat units —O—CH2—CH(—CH2—O—SO3−Li+)—, repeat units —O—CH2—CHR— in which R is H or CH3, optionally, repeat units —O—CH2—CH(—CH2R′)— in which R′ is a functional group. x Uses: electrolyte in electrochemical, selective-membrane and reference-membrane devices.
