Abstract

Alteration of the solubility of 4,4′-Hexafluoroisopropylidene diphtalic anhydride-4,4-oxydianline polyimide was investigated through experimental (the solubility experiments and equilibrium swelling) and theoretical (group contribution method by Fedors). In solubility experiments, total solubility obtained by a two dimensional representation (δv vs. δh diagram) was 21.23 (J cm-3) 1/2 . The range of total solubility determined from the equilibrium swelling method was between 22.71 and 22.99 (J cm-3) 1/2 . The total solubility of 6FDA-4,4′ODA polyimide calculated from the group contributions was 22.2 (J cm-3) 1/2 . The difference of solubility is slightly existed between experimental and theoretical method, but showed very good agreement.
