This work investigates the effects of the excluded volume and especially those of the chain stiffness on the structural and dynamical properties of a model polymer chain. The theoretical framework is the same as in the recent works by Steinhauser

et al

.

where a Rouse approach is adopted. Our model differs in that our chains have a finite average bending angle. As in the works by Steinhauser

et al

.

Langevin dynamic simulations were performed without hydrodynamic interactions. Whereas this doesn't impact the static properties we obtain

it also allows us to compare our results on dynamic properties to those predicted by Rouse theory

where hydrodynamic interactions are also neglected. Our results show that the structural properties are very sensitive to the chain stiffness

whereas the dynamic scaling laws remain the same as those by Rouse theory

with the prefactor depending on the persistence length.
