Abstract:A new shift factor has been introduced for representing dynamic viscoelastic data of polymer melts. I t has been shown that when the melt flow index is used as the shift factor, no arbitrary reference value is required and the coalesced curves are independent of temperature as well as of the grade of the polymer. The utility of the shift factor is demonstrated with high density polyethylene and polystyrene. The method can easily be extended to other polymers as well.
