Method of research - performance of work is carried out with use of modern radioanalytical methods (radionuclides X-ray fluorescent the analysis - RRFA and a method of radioactive indicators), of some physical and chemical metods. Key words - polyethyleneglycols, caesium perchlorat, method of radioactive indicators.For the first time the polythermal data on density, dielectric permeability of caesium perchlorate in the mixed solvents water - PEG?600 and water - PEG?1500 in a wide interval of concentration of the mixed solvent are received.It is established, that in researched systems a number of processes is realized: formation оcsonic ions, formation of association PEG?WATER due to specific interactions between moleculesН2О and polar groups PEG. It is shown, that the complex and not additive behaviour of solubility and thermodynamics of dissolution of caesium perchlorate in water systems PEG is caused a lot of factors: character of interpartial interactions in the mixed solvent and specific donor?aczeptic interaction caesium cation with PEG.
