WATER-SOLUBLE COMPLEX OF FULLERENE WITH POLY-N-VINYLPYRROLIDONE AND METHOD FOR PREPARING THESE COMPLEXES Russian patent published in 2005 - IPC

FIELD: chemistry of complex compounds, chemical technology.

SUBSTANCE: invention describes water-soluble complexes of poly-N-vinylpyrrolidone of molecular mass 24 000-67 000 Da with fullerene-C₆₀ in the content of fullerene-C₆₀ 1.1-2.7 wt.-% and to a method for their preparing. Method involves interaction of poly-N-vinylpyrrolidone of molecular mass 24 000-67 000 Da with fullerene-C₆₀ by mixing poly-N-vinylpyrrolidone solution of molecular mass 24 000-67 000 Da in chloroform with fulelrene-C₆₀ solution in ortho-dichlorobenzene in the ratio, wt.-% fullerene-C₆₀ : poly-N-vinylpyrrolidone of molecular mass 24 000-67 000 Da = 1.3:3.0 followed by removal of solvents and dissolving dry matter in water. Indicated complexes are designated for creature of water-soluble medicinal formulations and preparing fullerene-containing films from aqueous solutions.

EFFECT: improved method for preparing.
