摘要： The invention relates to a method for continuously producing polyamide oligomers. The method comprises continuously conveying an aqueous solution of polyamide-forming monomers from a storage vessel into an oligomerisation reactor, heating the aqueous solution beyond a dissolution or storage temperature, wherein the dwell time of the monomer solution in the oligomerisation reactor is limited in such a way and the pressure or the partial vapour pressure of the water is set in such a way that a conversion of monomers into polyamide oligomers does not exceed a maximum value and/or the produced polyamide oligomers do not phase-separate as a solid or spontaneously crystallise, and continuously discharging the polyamide oligomers from the oligomerisation reactor. A polyamide oligomer that can be produced in accordance with said method can be continuously provided in a mixture with water and then post-condensed into a polyamide in a method for producing a semicrystalline or amorphous polyamide that can be thermoplastically processed. Said polyamide can be used to produce shaped parts by means of injection moulding, multi-component injection moulding, injection moulding welding, extrusion, coextrusion, blow moulding, or deep drawing.
