Amphiphilic monomers with mixed-chain structures of the formula <IMAGE> 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. |
