Abstract

The rheological behaviour of oligoether acrylate blends with non-reactive analogues has been studied over the shear rate range 1–430 sec −1 and in the temperature interval 20–80°C. It is shown that oligoether acrylate composites are non-Newtonian liquids with anomalously high activational energy of viscous flow. The threshold values of the shear stress on reaching which there is passage to flow with constant viscosity have been evaluated. An attempt is made to explain the results in terms of the cibotaxic model of a fluid.
