Abstract: The invention relates to a method for producing polyamides. Said method is characterised in that the polymerisation of starting monomers is carried out in the presence of between 2.3 and 10 mmol - in relation to 1 mol of carboxamide group of the polyamide - of a compound used as a chain transfer agent, comprising a nitrile group and a functional group capable of forming a carboxamide group.

Abstract: Continuous polyamide production by three-stage reaction of an amino nitrile with water using a zeolite beta, layered silicate or titanium dioxide catalyst comprises performing the first stage in the presence of an organic liquid diluent. Continuous polyamide production comprises: (a) reacting at least one amino nitrile with water in the presence of an organic liquid diluent at 90-400 deg C and 0.1-35 MPa in a tubular reactor containing a Bronsted acid catalyst (I) selected from zeolite beta, layered silicates and titanium dioxide comprising 70-100 wt.% anatase and 0-30 wt.% rutile, in which up to 40 wt.% of the titanium dioxide can be replaced with tungsten oxide; (b) further reacting the product from (a) at 150-400 deg C and a pressure lower than that in step (a) in the presence of a catalyst of type (I) to form a gas phase and a liquid, solid or slurry phase, and separating the gas phase; and (c) contacting the liquid, solid or slurry phase with a water-containing gas or liquid phase at 150-370 deg C and 0.1-30 MPa. An Independent claim is also included for the polyamide produced by the process.
