Solubility Parameter Prediction of Polymers by Thermal Analysis

Solubility parameter of polymers is defined as the square root of the cohesive energy per cm3. For crystalline polymers, the cohesive energy is approximated by the sum of the heat of fusion, the heat of transition due to ordered parts in the amorphous regions, and the heat of glass transition. In this review, the methods to obtain these thermodynamic quantities by thermal analysis and as the background, the glass transition and the melting for polymers were discussed.
