Viscoelastic properties in terms of complex viscosity η*, storage modulus G' and loss modulus G" have been studied for wollastonite reinforced polypropylene com posites. The viscous response as well as the elastic response to changes in the frequency of dynamic oscillations have been fitted through appropriate rheological equations. The empirical parameters have been shown to be useful in estimating the viscoelastic properties of wollastonite reinforced polypropylene composites at loadings other than those studied in the present work.
