Abstract

Using a Langevin‐like approach, the deformation of a polymer, modelled as a bead‐spring chain, is calculated in simple shear, elongational and Kramers potential flow. Analytic expressions for the mean‐square end‐to‐end distance, radius of gyration, segment‐segment distance, static structure factor up to O(q^4^) and the intrinsic elongational viscosity are given. Near equilibrium, preaveraged hydrodynamic interaction is taken into account.
