Abstract
Using a Langevin-like approach, the deformation of a polymer, modelled as a bead-spring chain, is calculated in simple shear, elongational a nd Kramers potential flow. Analytic expressions for the mean-square en d-to-end distance, radius of gyration, segment-segment distance, stati c structure factor up to O(q4) and the intrinsic elongational viscosit y are given. Near equilibrium, preaveraged hydrodynamic interaction is taken into account.
