Abstract: A process for the continuous preparation of copolyamides in which (a) an aqueous solution of salts comprising equimolar amounts of diamines and dicarboxylic acids is passed under elevated pressure with simultaneous evaporation of water through a tubular precondensation zone to form a vapour phase and a prepolymer, at a temperature above the melting point of the prepolymer, (b) the vapour phase is separated from the prepolymer melt, (c) the vapour phase is separated in a column into steam and an aqueous diamine solution, and the diamine-containing aqueous solution is fed back into the polymerisation, (d) the prepolymer melt is mixed with molten caprolactam at polyamide-forming temperatures and (e) the mixture of prepolymer and caprolactam is passed from top to bottom through a vertical polymerisation tube at polyamide-forming temperatures, and a copolyamide is obtained.
