Hydrodynamic properties of star-shaped polystyrenes with a fullerene nucleus

The high-speed sedimentation, translational diffusion, and viscosity properties of star-shaped polystyrenes with a fullerene nucleus were studied in a dilute solution in benzene at 295 K. The molecular mass of the polymers was determined, and the hydrodynamic radius of a macromolecule and the branching number were estimated. The shape of star-shaped polystyrenes with a fullerene nucleus in solution is discussed. The experimental evidence is compared with the translational and rotational mobilities of graft polystyrene chains, linear polystyrenes with equal molecular masses, and fullerene C 60 .
