초록

In order to improve the wear resistance properties of lubricants, at least one compound of the following formula is incorporated therein: [Figure] (I) Rf is a perfluorinated radical, a=0 to 10, b=0 or 1 (if a=o and c=1), c=1 to 4 (2 if a≠0), m=0 or 1, n=0 or 1, X is an aryl radical, Y is a 2-hydroxy-1-phenylethyl group, R1 and R′1 each represent a hydrogen atom or an alkyl, cycloalkyl or aryl radical, R2 and R′2 each represent a hydrogen atom or an acyl residue, at least one of the symbols R1 and R2 being other than H or CH3 if the sum a+m+n=0.
