WebWhen a solvent is added to a crosslinked polymer, the polymer will swell. The amount of swelling depends on two factors: How soluble the (uncrosslinked) polymer is in the solvent - and as we have seen in the Polymer Solubility app, that's controlled by Flory-Huggins and the χ parameter;; The length (or, in this theory, the MWt) of the chains between crosslinks.
