Star-like fullerene C₆₀ derivatives with different branch number, synthesized by the reaction of fullerene with poly(vinylpyrrolydone) (PVP) macromolecules bearing the terminal amino-groups, were investigated in solution by the viscometry, dielectric, and electrooptical Kerr-effect methods in comparison with the ordinary linear PVPs of the same molecular mass. It was shown that covalent linkage of branches to fullerene through amino-groups leads to appearance of a polar and optically anisotropic nanoparticle (amine-substituted C₆₀) in the center of the coil of star-like polymers that radically changes dielectric and electrooptical properties of the initial polymer. Effect of fullerene on the dimension of polymer coil had been detected also.
