Solution properties of a new hybrid polymer (fullerene-containing polymer, FP) with a regular structure of macromolecules have been studied. In the starlike polymer molecule, six equal polystyrene chains and six poly(tert-butyl methacrylate) ones are attached as the arms to the fullerene C60 molecule used as a core. Hydrodynamic characteristics of the FP sample were compared with param eters of the six-arm star FP. The boundary profile in a low-speed sedimentation experiment obtained in several solvents with different refractive indices was analyzed to determine the inhomogeneity of the hybrid polymer sample.
