Abstract
The steady-shear flow birefringence of flexible polymers modeled as Gaussian chains has been studied. The influence of flow rate end chain length on the two important parameters in flow birefringence measurements, the extinction angle χ end the birefringence Δn, has been investigated, end the power laws obtained have been compared with theoretical predictions. Hydrodynamic interaction (HI) has been included by means of the Rotne-Prager-Yamakawa tensor, and the simulation results have been compared with the no-HI case. For low shear rates inclusion of HI reduces the influence of flow on Δn and tan 2χ, while for high flow rates the chain behaves as in the no-HI case due to the large separation between beads and thereby elimination of flow interaction
