WebThe Flory–Huggins theory plays an important role in assessing the mutual miscibility of the polymer and the plasticizer. The so-called Flory–Huggins parameter of mutual interaction is the criterion defining the miscibility of PVC with plasticizers. It allows for a quantification of the affinity of the plasticizer with the polymer.
