Abstract
The viscoelastic behavior of a weakly aggregating dispersion of polyst yrene latex is studied using dynamic rheological (low-amplitude oscill ations) and creep measurements. The high-frequency shear storage modul us and limiting Newtonian viscosity at low shear rates are determined as functions of the volume fraction of particles. The results are desc ribed by the microrheological theory proposed earlier and based on the analysis of the kinetics of the creation and the breakup of particle chains with account for the fractal properties of a structure.
