Abstract
The static and dynamic properties of a star polymer in a solvent at several densities have been studied by computer simulations using molecular dynamics. In addition to the repulsive Lennard-Jones potential which interacts between all particles we have used a harmonic potential to link 19 particles into a star polymer. It was found that both the static properties (e.g., the end-to-end distance and the radius of gyration) as well as the dynamic properties (e.g., the autocorrelation functions and the center-of-mass diffusion coefficient) are significantly influenced by the density of the solvent.
