METHOD OF MAKING SKI WAX Russian patent published in 2013 - IPC C09G3/00 A63C5/56 C07C17/278 C10M111/02 C10M105/52 C10M131/12 C10M129/76 C07C21/18 C10M129/74

Abstract RU 2500705 C1

FIELD: chemistry.

SUBSTANCE: perfluorocarbons are obtained by decarboxylation and dimerisation of C₆-C₉ perfluorinated acids, said perfluorocarbons being treated in 0.5-2 hours with ethanol or isopropanol solution containing 0.5-4.5 wt % fluorine-containing surfactants of general formula , where R_F is optionally a radical C₆F₁₃-, C₈F₁₇-, or , where n=1-2. The solvent is then distilled off, followed by drying and moulding.

EFFECT: use of the disclosed method provides a composition having a wide operating temperature range, which enables use of lubricants in unstable weather conditions.
