The invention relates to polychlorotrifluoroethylenes (PCTFE) for improving the gliding properties of sports equipment and, in particular, winter sports equipment, to compositions containing the same, and to their use for this purpose. The polychlorotrifluoroethylenes are, in particular, polychlorotrifluoroethylenes which have a molecular weight selected so that they have a pourpoint in the range from -70.degree. C. to 200.degree. C. (-94.degree. F. to 392.degree. F.), and preferably from 0.degree. C. to 100.degree. C. (32 to 212.degree. F.).
