FIELD: chemistry.
SUBSTANCE: there is disclosed water-soluble cation-active powdered polymer composition contains, at least, two cationic polymers of different molecular weight. The first cationic polymer consists of component monomers by radical polymerisation in aqueous solution with the second cationic polymer added whereat cation link types of the first and second polymers are matched. The first cationic polymer is a copolymer of cationic and nonionic monomers. Apparent molecular weight of the first cationic polymer is more than 1 million. The first cationic polymer is polymerised in aqueous solution of the second cationic polymer by adiabatic gel polymerisation method. Ratio of the second cationic polymer to the first cationic polymer is 0.01:10 to 1:3. Besides, there is described method of making these polymer compositions and their application as a flocculating additive for solid substance/liquid isolation.
EFFECT: developed effective method of producing water-soluble cationic polymer composition.
