Abstract: The invention relates to a method for the continuous production of copolyamides which are based on a lactame (I), a diamine (II) and a dicarboxylic acid (III). The inventive method is characterised in that a mixture (IV) containing a diamine (II), a dicarboxylic acid (III) and water is converted to a polymer in a first reaction area at a pressure of 1,3*10 5 to 2,5*10 5 Pa in the entry part of the reaction area, at a temperature above the melting point of the polymer (V) and with a degree of conversion of at least 80 % in relation to the molar quantities of diamine (II) and dicarboxylic acid (III), in that a mixture (VI) containing lactame (I) and water is converted to a polymer (VII) in a second reaction area at a pressure of 5*10 5 to 40*10 5 Pa, at a temperature above the melting point of the polymer (VII) and with a degree of conversion of at least 80 % in relation to the molar quantity of lactame (I), in that polymer (V) and polymer (VII) are then reacted with each other in a third reaction area at a pressure of 1*10 5 to 1,5*10 5 Pa in the entry part of the reaction area, at temperatures above the melting temperature of the polymer (VIII), to produce the polymer (VIII). Polymer (VIII) contains a maximum of 10 wt. % constituents that are extractable with water at a temperature of 95.degree.C, in relation to lactame (I), diamine (II) and dicarboxylic acid (III). The polymer (VIII) is then extracted with water so as to obtain the copolyamide. The invention also relates to copolyamides obtained using this method and to the ir use in the production of fibres, sheet structures and moulded bodies which are based on these copolyamides.

Abstract: The invention relates to a method for producing polyamides, their oligomers or mixtures thereof, optionally containing other reaction products, by reacting aminonitriles or dinitriles and diamines or a mixture containing aminonitril e, dinitrile and diamine and optionally additional polyamide-forming monomers and/or oligomers with water in a reactor (1) with a vertical longitudinal axis. According to said method, the reaction product is exfiltrated from the sump in the reactor (1) and accumulated ammonia and optionally other accumulated low-molecular compounds and water are drawn off via the head (2) . The invention is characterised in that the reactor (1) comprises at least tw o chambers (4) arranged in a longitudinal direction one above the other, that the chambers (4) are separated from one another by liquid-tight floors (5), that each chamber (4) is connected to the one (4) immediately below by a respective liquid overflow (6) and a liquid product stream is drawn off via the liquid overflow (6) of the lowest chamber (4), that the gas chamber (7) above the liquid level in each chamber (4) is connected to the respective chamber (4) lying immediately above it via one or several conduits (8), whic h open respectively into a gas diffuser (9) comprising orifices (11) for the discharge of gas below the liquid level. The reactor also comprises at least one respective deflector plate (12) positioned vertically around each gas diffuser (9), the upper end of said plate terminating below the liquid level and the lower end terminating above the liquid-tight floor (5) of the chambe r (4), thus sub-dividing each chamber (4) into one or more compartments suppli ed with gas (13) and one or more compartments without gas (14).
