Abstract
A new lubricant comprises at least one compound having a perfluorocyclobutane group, preferably a perfluorovinyl aryl ether. The lubricant is conveniently applied from solvents which are not chlorofluorocarbons and is effective at high temperatures e.g., in engines and for magnetic media, either internally or topically.
