    摘要: Process for the continuous preparation of prepolymers based on phenolic resin, an oxazoline component and an epoxide in the presence of a catalyst, including supplying the phenolic resin and the oxazoline component to an extruder in a stream A; a Lewis adduct of boron trifluoride or of aluminium trichloride, or arylsulphonic acids or alkylsulphonic acids, or latent arylsulphonic acids or latent alkylsulphonic acids, in a stream B, and the epoxide in a stream C, the infeed of stream A being situated, as seen in extrusion direction, before the infeed of stream C, these reactants are mixed at a reaction temperature of 120 to 200° C. with a residence time in the extruder of 3 seconds to 15 minutes, and then the product discharge of the extruder is cooled to a temperature of less than 45° C. within from 30 to 60 seconds.
