FIELD: chemistry.
SUBSTANCE: invention relates to new compounds of formula
where R1 represents H or CH3; R2, R3, R4 represent 4-R3piperazine- or R4R5N; R3, R4, R5 - same or different C1-C4 alkyl groups with straight or branched chain; n=2, 3, …, 20, and to a method for their preparation. Compounds of formula I contain easily polymerizable (meth)acryloyl group and a number of ionic groups and therefore can be used as monomers for the preparation of polyelectrolytes.
EFFECT: increased exchange capacity.
