WebA modification of the extended Hansen method, formerly used to determine the partial solubility parameters of drugs and non-polymeric excipients is tested with a polymer for the first time. The proposed method relates the logarithm of the intrinsic viscosities of the polymer in a series of solvents and solvent mixtures with the Hansen (three ...
WebSolubility parameter. ' Polymer solutions occur in two stages. — Initially, the solvent molecules diffuse through the polymer matrix to form a swollen, solvated mass called a gel. — In the second stage, the gel breaks up and the molecules are dispersed into a true solution.
