Abstract

The dynamic behavior of the fullerenol-based polyurethane star-shaped polymer and its analog model stars, containing three or four polymer arms, was investigated in toluene solution by dynamic light scattering measurements. In these systems, the diffusion coefficients clearly showed no angular dependence. In the case of study in dilute solution, all three star polyurethanes were found to possess higher mobility than that of the corresponding linear polyurethane with a similar molecular weight. Furthermore, the conformation of anchoring polymer chains was characterized by the hydrodynamic shrinking factor and compared with the Gaussian model. Results suggested that the polymer arms in the fullerenebased star-polymer were uniformly distributed around the central C60 cage.
