WebThe solubility of a polymer in organic solvents can be explained by the solubility parameter (δ) theory, which is a useful prediction for non-polar and slightly polar polymers (Quesada-Medina et al. 2010). According to Hildebrand’s theory, the solubility of a polymer in a solvent is defined as the square root of the cohesive energy density (Eq. WebAbstract. Solubility of a polymer in a solvent, which is the most important property for polymer fractionation, depends generally on the chemical structures of both polymer and solvent. The old rule “ similia similibis solventur ” (solubility results from similarity) may give useful hints to select solvents for a polymer.
