Abstract
The methods of HPLC, TLC, UV spectroscopy, H-1 and C-13 NMR spectroscopies, viscometry, and translational diffusion measurements are used to study the interaction of C-60 fullerene with poly(N-vinylpyrrolidone) in two systems : a blend of individual components and a fullerene-containing copolymer, It is established that sufficiently strong donor-acceptor complexes are forme d between the components. Complex formation is accompanied by a local chang e in the polymer chain conformation. As a result, several chain units are i nvolved in the interaction with a fullerene molecule. Light-scattering meas urements show that in dilute aqueous solutions fluctuation associates are f ormed with participation of a solvent because of the structuring action of fullerene.
