Abstract
The invention relates to a process for preparing maleic polyelectrolytes containing piperazine rings. According to the invention, the process consists of the interaction of some bi- or ter-copolymers of the maleic anhydride with monomers, such as N-vinyl pyrrolidone, vinyl acetate, styrene, methyl methacrylate, with piperazine or derivatives thereof, in water or organic solvents, at a temperature of 20...80°C, for 2...12 hours.
