Solubility parameter of polymers
WebThe solubility parameter for a polymer is calculated through its components by using the contributions of chemical groups reported in the literature with the resultant values found … The Hildebrand solubility parameter (δ) provides a numerical estimate of the degree of interaction between materials and can be a good indication of solubility, particularly for nonpolar materials such as many polymers. Materials with similar values of δ are likely to be miscible.
