FIELD: chemistry.
SUBSTANCE: invention relates to polymers containing fluorosulfonyl groups. Polymer is proposed, containing fluorosulfonyl groups with links of the formula u1, where RF1 and RF2 are C1-3 perfluoroalkylene group. Polymer is also proposed, containing sulfonic acid groups obtained from fluorosulfonyl groups, as well as its production method and its use for the production of membranes.
EFFECT: proposed polymer has increased stability in storage and is suitable for the production of membranes with high ion-exchange capability and improved mechanical strength.
