Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a phenol resin-based prepolymer, which has good solubility in a ketone and has a melting point below 100°C.SOLUTION: In the method for continuously producing a phenol resin-, oxazoline- and epoxide-based prepolymer in the presence of a catalyst by using an extruder, a phenol resin and an oxazoline component as a substance flow A, a Lewis adduct of boron trifluoride or aluminum trichloride, an arylsulfonate, an alkylsulfonate, a latent arylsulfonate or a latent alkylsulfonate as a catalyst as a substance flow B, and an epoxide as a substance flow C are fed to an extruder, wherein: an inlet for the substance flow A is located before an inlet for the substance flow C when viewed in the extrusion direction; the starting materials are sufficiently mixed in the extruder at a reaction temperature of 120 to 200°C and in a residence time of 3 sec to 15 min; and a discharged product from the extruder is cooled to a temperature of
