A new approach for scaling the viscosities of glass forming liquids based on 'fragility' has been proposed. The required fragilities have been theoretically evaluated. The scaling function used here contains only fixed parameters. However, the collapse of viscosity data improves remarkably when both fragility and limiting high temperature viscosities are slightly adjusted. The physical significance of scaling viscosities using fragilities and the implied relation between activation barriers in the present approach and Adam–Gibbs entropy theory have also been discussed.
