Sažetak
The theoretical approach to modeling phase equilibria of polymeric systems should take into account information on their interactions. In polymer systems both intra- and intermolecular interactions are present and they should be modeled. The mutual combining of differential interactional models is discussed. Once the interaction model is selected, the different techniques allow us to cast the thermodynamic properties obtained by the model in comparison by experimental data. A comparison of theoretical results and experimental data will inevitably reveal discrepancies. As the selected models are approximate it may be a problem to identify the principal origin for the observed deviations. Hence, it is of essential importance to improve theories. In case the selected model is not appropriate it is not productive to refine the theoretical evaluation but one should concentrate on the selection of an advanced model. With the improvement of modeling techniques and studies it has become possible to obtain essentially very good thermodynamic frameworks for different purposes. A comparison of the level of theory and modeling will reveal the consequences of the theoretical approximations involved. A comparison of calculation and experimental data can provide information on the appropriateness of the chosen model. In this contribution several illustrative examples are given, demonstrating how such comparisons can help to improve the theory as well as to define appropriate interaction models for polymer systems.
