Modification of TM EOS and application to PPO-PS blend using glass transition data

Blending of polymers is a technique to obtain properties in thermoplastic materials not readily achieved in a single polymer. Virtually all technologically important properties can be improved in this way, some of the more important ones being flow properties, mechanical properties (especially impact strength), thermal stability, and price. Polymer blends can form single –phase or multiphase solids and melts. For polymeric substances, equations of state are also an important subject for scientists and polymer engineers because such equations are able to predict the behavior of polymers in a wide range of temperature and pressure particularly when experimental data are scare. In this study, the volumetric properties of poly (۲,۶-dimethyl phenylene oxide)+polystyrene (PPO/PS) blend are predicted by Tao-Mason equation of state (TM EOS) using glass transition data in different temperature, pressure and mole fractions.
