How does the polymer-solvent interaction influence the solution properties/ 3. To what applications do the interesting properties of polymer s olutions lead? -General rules foe polymer solubility: 1. Like dissolve like; WebAug 1, 2003 · The solubility of a given polymer in various solvents is largely determined by its chemical structure. Polymers will dissolve in solvents whose solubility parameters are not too different from their own. This principle has become known as ‘like dissolves like’, and, as a general rule, structural similarity favors solubility.
