solubility parameter method to predict miscibility of polyblends. The three dimensional method attempts to account for the combined effects of dispersion, polar, and hydrogen bonding interactions between molecules. This study focused mainly on the miscibility of blends of poly. with homopolymers as .

solubility parameters provide a quantitative measure of these interactive forces. By using CO ACTsM service, a computer program designed for solvent systems with various resins, plasticizers were found to lie near the edge of the solvency "sphere" of PVC. The relative positions of various plasticizer structures are in the .
that related the solubility parameter of the components of the polymer–ingredient–liquid system with lg D0. It can be concluded that the proposed equation makes it possible to estimate the effective activation energy of diffusion of DOP in PVC during the extraction of the ingredient with alcohols and hydrocarbons.
17 Aug 2019. It illustrates the advantages of using Maple to estimate Hansen solubility parameters and to predict the polymer solvent miscibility. The study focuses on the. The figures show that DMF has a good compatibility for all the polymers except for PVC, which exhibits high resistance to all the tested solvents.

ties of samples prepared from PVC compounds containing solvents depend on the solu bility parameter of the solvent used. Solvents with a solubility close to that of PVC have the same effect as plasticizers. Solvents with very high solubility parameters,. e.g., water, influence the flow and dynamic properties in just the .
Hansen Solubility Parameters HSP introduced in Prof Steven Abbott's Practical Solubility science apps.
The Hildebrand solubility parameter 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.
Dimethyl Sulfoxide , one of the strongest organic solvents, has been used commercially for several decades. It is an effective solvent for a wide array of organic materials, including many polymers. DMSO also dissolves many inorganic salts, particularly transition metals nitrates, cyanides and dichromates. DMSO is .

to control its solubilizing effect; if a plasticizer is too polar, it can destroy PVC crystallites; if it is too non polar, compatibility problems can arise. Useful tools in estimating plasticizer compatibility are the Apolar Polar Ratio method developed by Van Veersen and Meulenberg.  and the solubility parameter methods [8–11].
