Abstract
A lubricant provides enhanced performance at high temperatures, along with a higher evaporation temperature, where the main-chain includes a moiety with a rotational energy barrier that is higher than CF. The lubricant has the general Formula (I): wherein Rc is a multivalent central group, Rb is a main chain group having a constituent with a higher rotational energy threshold than CF, Re is an end group having at least one anchoring functional group, m is from 2 to 50, and n is from 2 to 8. The constituent with a higher rotational energy threshold than CF, may be a substituted or non-substituted aromatic group.
