    Abstract: Amphiphilic monomers with mixed-chain structures of the formula in which Y denotes -O- or -NH- X denotes a group of the formula -(CH2)n- or -(CH2-O-CH2)n- l denotes an integer from 0 to 10, n denotes an integer from 1 to 10, R1 denotes hydrogen, methyl, chlorine, cyano, fluorine or bromine, R2 denotes C1-C24-alkyl or C1-C24-fluoroalkyl and R3 denotes C8-C24-alkyl or C8-C24-fluoralkyl, with the proviso that the groups R2 and R3 contain a different number of carbon atoms. The monomers are polymerized on their own or together with other comonomers. The polymers obtained are suitable for the preparation of ultra-thin layers on a suitable layer support.

    Abstract: Polyamides of the general formula [N(A)-X-N(B)-CO-Y-CO-]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 C1 to C26 alkyl group and n denotes an integer greater than 4. The said polyamides contain at least one alkyl group of C6 to C26 per repeating unit. The groups X and/or Y contain at leat one CH2 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.
