The influence of the solubility parameter on the regularities of obtaining polymer dispersions based on copolymers of 2-hydroxyethyl methacrylate and glycidyl methacrylate are investigated. A method of nucleating polymerization for obtaining micron-sized monodispersed spherical materials is proposed. The influence of the nature and amount of solvent on the dispersion characteristics of the polymer particles has been established. The selection of an effective dispersion medium for the polymerization of НЕMА and GMA was made. Comparative studies of the polymerization of monomers of different hydrophilicity and solubility have shown that the size and dispersion of the particles are greatly influenced by the hydrophobicity of the monomer.
