    Abstract: Thin films are produced by a process in which organic polymers having long-chain side groups are dissolved in an organic solvent, the solution is spread at the water/air interface by the LangmuirBlodgett technique and the film is transferred onto a solid base material after evaporation of the organic solvent, and the organic polymers used are those which contain longchain n-alkyl side groups bonded to the main chain of the polymer via polar groups, and some of these long-chain nalkyl side groups are replaced by shorter-chain n-alkyl side groups, by branched alkyl side groups having the same or a smaller number of carbon atoms or by equally long or shorter side groups having one or more C-C multiple bonds. This process can be used to produce film elements, for example for optical filters.
