The invention relates to liquid light guides, consisting of a tubular sheath, an inner coating of said sheath and a light-conducting liquid inside the sheath. Novel perfluorinated homo- or copolymers are used for the inner coating, said homo- or copolymers containing dioxoles of general formula (I), wherein X1, X2, X3, and X4 have the following meanings: X1 and X2 represent F or CnF2n+1, independently of each other and X1 or X2 also represents O-CnF2n+1, and X3 and X4 represent F, CnF2n+1 or O-CnF2n+1 independently of each other, n being a whole number from 1 to 5. Fluorodioxoles in which X1 and X2 represent CF3 and X3 and X4 represent F are excluded. |
