Continuous process for the production of polyamides, their oligomers or mixtures thereof, if necessary, with additional reaction products, by the reaction of aminonitriles or dinitriles and diamines or mixtures thereof, if necessary, together with monomers and / or oligomers additional forming polyamides, with an aqueous medium from aqueous extracts of monomers and oligomers, obtained in the production of polyamides during the extraction of the polymer with water, in a reactor with vertical longitudinal axis, essentially run in the longitudinal direction, introducing water and / or the aqueous medium in the reactor at least two different points along the vertical longitudinal axis, the aqueous medium being introduced at least one point. |
