الوصف: The results of studies on the influence of the nature of the solvent on the kinetics of the radical polymerisation of water-soluble monomers are surveyed. It is noted that the rate of the process and the chain propagation rate constant in the polymerisation of monomers of this kind change sharply on passing from organic solvents to aqueous solutions. Comparative analysis of the kinetic data and the results of spectroscopic and viscometric studies made it possible to put forward a mechanism for the polymerisation of water-soluble monomers in various solvents. A distinctive feature of the polymerisation of water-soluble monomers is the hydrophobic interactions arising in aqueous solutions of the polymers and leading to a sharp difference between the kinetic parameters of the polymerisation of monomers of this class in water and organic solvents. The bibliography includes 76 references.

الوصف: The influence of the solvent on the rate of radical polymerisation and copolymerisation, observed and investigated in the last ten years and caused mainly by a change in the rate of the elementary chain propagation reaction, is discussed. The published data on the polymerisation and copolymerisation of a number of monomers in solvents of different types are surveyed. Attention is drawn to the fact that the greatest effects are observed for polar monomers, particularly for water-soluble monomers in an aqueous medium. The causes of the change in the overall rate of reaction, the constants kp, and the copolymerisation constants for different monomers are examined. The bibliography includes 104 references.
