FIELD: lubricants.
SUBSTANCE: additive is composed of perfluoropolyoxaalkylene derivatives with molecular weight ≥ 2000 having general formula RFR'FQX, where RF represents fluoroalkoxy group from CF3O- to C8F17O-; R'F represents general formula -(Y-CFX-CF2O)n-CmF2m, in which Y is CF2, X is F, Y = zero, X is F or CF3, n=10-80, and m=1-2; Q is CO-, SO2- or -CH2-; Z is -OH, -N(RH)p, and RH represents C1-C8-alkyls, -(CH2CH2O)kH (k=1-5) or -HN(CH2)qN(R'H)2 with q=1-4 and R'H is the same as RH.
EFFECT: enhanced antiwear and antiscoring properties.
