THE PECULIARITIES OF FREE-RADICAL POLYMER IZATION OF WATER-SOLUBLE MONOMERS

The results of the study of the solvent nature influence on the kineti c peculiarities of the free-radical polymerization for water-soluble m onomers have been summarized. The dramatic change in the rate of proce ss for the polymerization of such monomers has been noted while using water solutions instead of organic solvents. Comparative analysis of t he kinetic data and the results of spectroscopics, as well as viscosim etric, investigations, allowed one to propose polymerization mechanism for water-soluble monomers in different solvents. The distinctive fea ture of water-soluble monomers polymerization is hydrophobic interacti on, which takes place in water solutions of polymers and results in sh arp differense between kinetic parameters for such monomers polymeriza tion in water and organic solvents.
