ResumoAbstract The compatibility of suspension PVC with various plasticizer blends was determined by means of calculated compatibility predictors, such as solubility parameters and polarity parameters, as well as actual measurements of compatibility. Then, with a torque rheometer, the temperature at the fusion peak was obtained for various PVC/plasticizer blend compositions. Finally, empirical equations were derived to relate compatibility parameters with the temperature at the fusion peak, predicting the effect of plasticizer blend on processability.
