Abstract: The invention relates to a method for the production of composite elements comprising at least one outer layer a) and a layer b) firmly bonded to it, an adhesion promoter c) being applied between the outer layer a) and the layer b) firmly bonded to it, the outer layer a) being continuously moved and the adhesion promoter c) and the layer b) firmly bonded to it or the starting materials thereof being applied in succession to the outer layer, the application of the adhesion promoter c) being effected by means of a rotating disk which is mounted horizontally or with a slight deviation from the horizontal of up to 15°, wherein the rotating disk is provided with teeth on the edge.

Abstract: In a process for producing polyamides by polycondensation of polycondensable polyamide-forming monomers and/or oligomers in reaction mixtures comprising same, which may be water-containing but are free from organic solvents, the polycondensation is effected in an agitated reactor under agitation in a first step in the liquid phase and after a phase change taking place during the process in the same reactor is effected in a subsequent second step in the solid state, wherein the temperature in the reactor is below the melting point of the polyamide in the second step at least.
