| 摘要 |
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. |
