ABSTRACT:
Novel polyfluorinated cyclic carbonates of the formula ##STR1## in which R.sub.F is an unbranched or branched perfluoroalkyl radical having 1 to 18 carbon atoms, an unbranched or branched .omega.-hydro- or .omega.-haloperfluoroalkyl radical having 1 to 18 carbon atoms, or a cycloperfluoroalkyl radical having 4 to 6 carbon atoms, are described. They are prepared by reacting a polyfluorinated halohydrin of the formula R.sub.F --CH.sub.2 --CH(Hal)--CH.sub.2 OH, in which R.sub.f has the meaning mentioned and Hal represents a halogen, with carbonate or hydrogen carbonate compounds in the presence of an aprotic solvent. The novel compounds, which are generally solid and crystalline at room temperature, represent, in particular, good waterproofing and oil-proofing agents for textiles.
