We study the equilibrium dynamics of a single polymer chain under goodsolvent condition. Special emphasis is laid on varying the drag forceexperienced by the chain while it moves. To this end we model the solvent in amesoscopic manner by employing the Lowe-Andersen approach of dissipativeparticle dynamics which is known to reproduce hydrodynamic effects. Ourapproach captures the correct static behavior in equilibrium. Regarding thedynamics, we investigate the scaling of the self-diffusion coefficient $D$ withrespect to the length of the polymer $N$, yielding results that are compatiblewith the Zimm scaling $D \sim N^{-3/5}$.
