Abstract
Study was made to determine the relation between the introduction of the perfluorooctyl group (Rf) into epoxy resin and its properties. When Rf was present at a few % in acidanhydride-cured epoxy resin, its contact angle increased by 20 degrees. Compounds examined in this study to introduce Rf groups into epoxy resins were (1) : 8 (9) - [2- (perfluorooctyl) ethoxy] tricyclo [5.2.1.02, 6] decane-3, 4-epoxide and (2) : a derivative of (1) which had a hydroxyl group. When reacted with acid anhydride to preparate acid-anhydride-cured epoxy resin, (1) did not react with the anhydrides, whereas (2) was successfully incorporated into the resin.
