PURPOSE:To obtain the titled resin excellent in the surface characteristics such as water and oil-repelling properties, antifouling property and friction properties and suitable also in a water and oil-repelling agent, etc., by reacting a phenol resin with a specific perfluoroalkene in the presence of a basic catalyst. CONSTITUTION:A phenol resin is reacted with a perfluoroalkene expressed by the formula Rf-F {Rf is perfluoroalkenyl expressed by formula I [R1-R3 are perfluoroalkyl expressed by the formula -CnF2n+1 (n is 1-6)]} in the presence of a basic catalyst (preferably tertiary amine such as trimethylamine) to provide the aimed resin replacing a phenolic OH group of the phenol resin with a fluorine-containing ether substituent group. As the perfluoroalkene, e.g. hexapropene oligomer expressed by formula II is preferably used.
