摘要：
The size characteristics and formation kinetics of selenium-containing nanosystems based on various polymeric matrices (nonionic polymers: polyvinylpyrrolidone, oxyethylated cellulose; cationic polyelectrolyte: poly-N,N,N,N-trimethylmethacryloyloxyethylammonium methyl sulfate; anionic polyelectrolytes: poly-2-acrylamido-2-methylpropanesulfonic acid, polymethacrylic acid) were studied by methods of molecular optics and spectrophotometry. The influence of the nature of the polymeric matrix and of the selenium: polymer weight ratio on the rate constant and hydrodynamic radius was determined.
