Solubility of polymers in solvents

WebPolymers and Packaging. Determining the diffusion rate of solvent molecules through a polymer is vital in polymer processing, analysis, and performance. Another characterization that can be studied is the solubility parameter which is directly related to the cohesive energy density of a material. WebA number of quasibinary sections (stepwise addition of the second solvent to given solutions of the polymer in the first solvent) for a sample (M = 110000) of high molecular uniformity yielded a cloud point surface which gives “island curves” (closed solubility gaps) for constant temperatures between the critical temperature of DMF/CH and the top of the …
