    摘要： In order to continuously produce an ultrathin, ordered layer of amphiphilic molecules on the surface of a polar liquid a directed flow of the polar liquid is produced in a duct which contains the amphiphilic molecules in dissolved or undissolved form on the surface in spread form. In the duct, a duct section having a relatively high flow rate on the surface and comprising a ramp which is arranged at the bottom of the duct and washed over by the polar liquid is provided. This is followed by a duct section having a relatively low flow rate on the surface, in which the flow is dammed up at an obstacle at a liquid level constant with time, so that an ultrathin, ordered layer of amphiphilic molecules is continuously formed in these duct sections at the polar liquid/air interface by compression of the flow. The washed over ramp is movable.

    摘要： Polyamides of the general formula [N(A)-X-N(B)-CO-Y-CO-].sub.n are described, in which Y denotes a divalent group, X a divalent radical whose chain contains at least two carbon atoms, A and B independently of one another denote H or a C.sub.1 to C.sub.26 alkyl group and n denotes an integer greater than 4. The said polyamides contain at least one alkyl group of C.sub.6 to C.sub.26 per repeating unit. The groups X and/or Y contain at leat one CH.sub.2 group in the chain. The polyamides are prepared by reaction of a diamine of the formula NHA-X-NHB with an about equimolar amount of a reactive derivative of a dicarboxylic acid of the formula COOH-Y-COOH. The polyamides obtained can be used in order to prepare highly ordered monomolecular LB films on a support. For this purpose, the polyamide is dissolved in a volatile organic solvent which is immiscible with water and the solution is spread on the water/air interface. After evaporation of the solvent the layer is compressed and transferred to a solid support by the LB technique. The film is very stable and can be used to prepare optical waveguide systems, filters for optical purposes or protective layers.
