Abstract: The invention relates to a process for continuously preparing polyamide oligomers. This comprises continuous conveying of an aqueous solution of polyamide-forming monomers from a reservoir vessel into an oligomerization reactor, heating of the aqueous solution beyond a dissolution or storage temperature, the residence time of the monomer solution in the oligomerization reactor being limited and the pressure or the partial vapor pressure of the water being adjusted such that a conversion of monomers to polyamide oligomers does not exceed a maximum value and/or the polyamide oligomers formed do not phase-separate or spontaneously crystallize in solid form, and continuous discharge of the polyamide oligomers from the oligomerization reactor. A polyamide oligomer preparable by this process can be provided continuously in a mixture with water in a process for preparing a semicrystalline or amorphous, thermoplastically processible polyamide and then postcondensed to give a polyamide. This polyamide can be used for production of moldings by means of injection molding, multicomponent injection molding, injection molding/welding, extrusion, coextrusion, blow molding or thermoforming.

Abstract translation: 本发明涉及连续制备聚酰胺低聚物的方法。 这包括将聚酰胺形成单体的水溶液从储存容器连续输送到低聚反应器中，将水溶液加热超过溶解或储存温度，单体溶液在低聚反应器中的停留时间受限制，压力 或调节水的部分蒸气压使得单体向聚酰胺低聚物的转化率不超过最大值，和/或形成的聚酰胺低聚物不以固体形式相分离或自发结晶，并且连续排出聚酰胺 低聚反应器的低聚物。 通过该方法制备的聚酰胺低聚物可以在制备半结晶或无定形，热塑性可加工聚酰胺的方法中与水的混合物连续提供，然后进行缩合以得到聚酰胺。 该聚酰胺可用于通过注射成型，多组分注射成型，注射成型/焊接，挤出，共挤出，吹塑或热成型来生产模制品。
