FIELD: chemistry.
SUBSTANCE: group of inventions relates to technology of preparing a dispersion of a water-soluble polymer which can be used as a retention and dehydrating additive during production of paper, as an additive which increases strength of paper in dry state, as a thickener in chemical, biotechnological, pharmaceutical or cosmetic industry or as a soil-improving additive. The method of preparing a dispersion of a water-soluble polymer involves polymerisation of one or more water-soluble anionic monomers and one or more non-ionic vinyl monomers present in a reaction mixture which is an aqueous medium which additionally contains a polymer stabiliser (B) and a polymer co-stabiliser (C). Disclosed also is a polymer dispersion composition and a method of making paper using the said dispersion.
EFFECT: invention enables to obtain a dispersion of a water-soluble polymer which is characterised by high stability and high content of active substance.
