PURPOSE: To provide a crosslinking product which is like wax and insoluble in solvent, by crosslinking through direct C-C bond perfluoro-polyether chains which are produced by treating specific perfluoro-polyether using ultraviolet radiation and have specific functional group. ;CONSTITUTION: By treating by using ultraviolet radiation perfluoro-polyether which has structure represented by the following formula I (Rf, R'f are groups represented by formulas II, III; m, p are at least 1 and m≥p; r is 0 or positive integer, and r≤p, m/n is 0.5-2), has at least 3 COF groups represented by formula IV along and in one end or both ends of perfluoro-polyether chain, and has molecular weight of 800-15000, and by crosslinking perfluoro-polyether chains with direct C-C bond between carbon atoms, the aimed crosslinking product which is suitable for ion exchange resin and catalysis carrier is provided.;COPYRIGHT: (C)1990,JPO
