摘要：

The reaction of polyvinylpyrrolidone with sulfophthalein dyes was studied by spectrophotometry. The dependence of Delta pH(1/2) of the formation of adducts on the concentration and molecular mass of polyvinylpyrrolidone was determined. The ratio of components in adducts was determined. The effect of electron-donor and electron-acceptor substituents in dyes on Delta pH(1/2) was studied. A procedure for determining polyvinylpyrrolidone in the Gemodez-H pharmaceutical was proposed.
