| Abstract: | The statistical theory of temporary polymer networks is an effort of describing the macroscopic behavior of such networks based on molecular behavior analysis. The calculation of the stress tensor of a network and the satisfactory comparison with experimental viscosity results was shown before Rheol. Acta 28 (1989) 193]. Here we present the foresights of the theory as regards flow birefringence. The polarizability tensor is calculated first and then the birefringence of a four-functional temporary polymer network is estimated for a stationary simple shear flow. The dependence of the calculated quantities on shear rate is in line with existing experimental evidence. |
