โœฆ Synopsis

The classical free volume theory is modified semi-empirically to derive an expression useful for predicting the glass transition temperatures (T~) for compatible polymer blends. This equation produccs values of T~ in better agreement than those from the Kelley-Bueche equation with the dilatomctric data for f e of a number of plasticized polymers. The improvement is primarily attributed to the consideration of intermolecular interactions in the present investigation.

Based on free volume, an equation has been derived enabling calculation of glass transition temperature (To) of plasticized polymers, knowing the plasticizer content, the thermal expansion coefficients and values of To of the polymer and plasticizer. Determined and calculated TO are in satisfactory
