A New Improved Method for Estimating Hansen Solubility Parameters of Polymers

In this work a new improved method to estimate the Hansen solubility parameters, δd, δp, and δh, as well as the radius of interaction sphere for a given polymer, is presented starting from the idea that the solvents that dissolve a polymer have solubility parameters near to that polymer. In this study, using intrinsic viscosities of the polymer in these solvents and the molar volumes of the solvents, a correlation has been done. Results fit data quite well.
