dispersion polymerization

The impact of the vinyl monomers nature, concentration, and temperature on the kinetics of dispersion polymerization in the presence of polyvinylpyrrolidone was studied. The optimal technological parameters of the copolymer synthesis process are determined. It is defined that the properties of dispersion polymerization depend on the process conditions.

Metal-complex macroinitiators were successfully applied for the synthesis of polymer nanocomposites with core-shell structure by two-stage water dispersed polymerization. On the first stage, formation of monodispersed polymer particles of desired size and functionality is achieved by target variation of macroinitiator concentration, content of metal cations in its structure, and pH of medium. Initiation of grafted polymerization from the surface of seeded particles is provided by residual peroxide moieties of macroinitiator.
