摘要：

An off-lattice bead model with a hard-spheres potential is used to characterize the two-body properties of star polymers of functionalities f = 4-18 in good solvent conditions through Monte Carlo simulations. The second virial results complement a previous study performed with a Lennard-Jones potential. Some intrinsic viscosity numerical data are also obtained. The second virial coefficient and viscosity data are combined in terms of a single parameter, with apparently anomalous features in terms of the star functionalities which are also observed from existing experimental data. The effective intermolecular potential is compared with a global potential recently proposed. (C) 2000 Elsevier Science Ltd. All rights reserved.
