“…Early works by Payne and Whittaker [1] on the oscillatory shear flow and by Vinogradov et al [2] in the steady shear flow were con cerned with elastomer/CB mixtures. Various features of their behavior were attributed to the particle parti cle interactions and breakdown of aggregates.…”

Rheology and viscoelastic behavior of polystyrene (PS)/silica microcomposites and nanocom posites were studied. The apparent viscosity, transient shear stress growth after startup shear flow and stress relaxation after cessation of flow at various shear rates, the complex dynamic viscosity, the storage and loss moduli at small and large strain amplitudes and various frequencies were performed. The effect of size, shape and volume concentration of silica was discussed. The maximum volume concentration, corresponding to the concentration at which the relative viscosity of mixtures goes to infinity, with respect to the hydrodynamic contribution of the particles and to polymer-filler interactions was obtained. The difference between the yield stress and residual stress is shown. The domain of equivalence between the apparent viscosity as a func tion of the shear rate in steady state flow and the complex dynamic viscosity as a function of the strain rate amplitude in highly nonlinear region of oscillatory flow was established. The viscoelastic behavior was inter preted based on the morphology of microcomposites and nanocomposites observed by SEM.

“…However, the existing relations are applicable either to individual systems, or have a large number of fitting parameters [3,5]. The present study is an attempt to give a general description of the flow of polymeric compositions containing a high-disperse filler, based on a number of quantitative relationships and experimental data that have appeared in the literature in recent years [1,3,[5][6][7][8][9][10][11][12][13]. The compositions considered are given in Table 1.…”

“…Carbon black, silica, high-disperse chalk, etc., represent such fillers. The existence of a yield stress which is a complicated function of concentration and filler particle size is typical of the above-cited compositions [1][2][3]. The viscosity of such compositions depends also on the rheological properties of the polymer matrix [1].…”

Analysis of literature data on the flow of polymeric and oligomeric compositions as well as on systems of low viscous dispersion media containing a high-disperse filler (carbon black, silica, high-disperse chalk) has been carried out. As the basic idea, a proposal is made that their viscosity anomaly is due not to the matrix viscosity anomaly, but to the gradual breakdown of the filler structural skeleton with increasing shear stress z and shear rate ~. The viscosity anomaly of those compositions is determined by the zeroshear but not by the apparent matrix viscosity. A general relationship has been found to describe the flow of such systems depending on the zero-shear matrix viscosity values, r/o, their yield stress, z x, and filler volume concentration ~0: r = ry + K~0//~J) ~, where K = 4.9 and n = 0.69 are constants.
