AbstractNew water-soluble polymers with phosphate groups based on 2- methacryloyloxyethyl phosphate have been synthesized by copolymerization with 1-vinyl-2-pyrrolidone and 1-vinylimidazole. The obtained copolymers are polyelectrolytes showing high inclination to aggregation in aqueous medium according to light scattering data. Copolymer of 1-vinylimidazole shows ampholyte properties with isoelectric point at pH 6.8 (6.4 in 0.1M NaCl). Condensation of silicic acid in the presence of this copolymer results in composite particles containing aggregated or non-aggregated copolymer coils with embedded silica.
