There is a correlation between the solubility parameter of solvents and the polymer swelling observed in those solvents. You could find interesting the following paper:

Hildebrand solubility parameter (δ) is frequently used by polymer scientists as it corresponds to a measure of the intermolecular attractive forces of solvents, and therefore could relatively well predict solubility of materials (eg a polymer) in a solvent. As mentioned in the answer above, solvents (or a solvent and a polymer) having similar δ values  show high probability to be miscible. In those cases of solvents showing close δ values with the polymer of interest, one could expect increased polymer swelling.

Now with regard to the use of dielectric constant as a measure of degree of swelling of a polymer, as for solvents of low dipolarity the dielectric constant could be correlated to δ, Ι suppose that one could notice a corresponding correlation between solvent dielectric constant and polymer swelling.  

Dear Sir;

the popular idiom says "like dissolves like", swelling is the action of the diffusion of the solvant in a matrix, it occurs when the solvant does not have sufficient solvation power or the matrix is partially crosslinked (cured). A measure of the solvant power for solvation is the dielectric constant or polarity or more practically the solubility parameter, and compared to those of the polymer under investigation. The closest values are, the more swelling or even solubilization are likelly to occur. Regards

Dear all;

this review paper gives the necessary background of polymer-solvant interaction. Regards

Thanks for valuable suggestion

I have worked on similar area and finally concluded there is no simple relation exist. Please see my poster on this!
