Viscosity and glass temperature relations for polymer-diluent systems

Authors


Abstract

Expressions are derived from free volume considerations which predict the concentration dependence of viscosity and glass temperature for polymer-diluent systems. Experimental data for several systems were examined and general agreement with theory was found over broad ranges of concentration. Particular emphasis is placed on the limited amount of information required for the application of these expressions to describe the viscous properties of polymer-diluent systems.
