Compounds suitable for being used as lubricants, having the general formula
or
where
R = -CF3, -C2Fs, or -C3F7;
X = F, or -CF3;
R" = F -CF3, or -C2F5;
m = an integer from 3 to 100;
n = a finite integer, or zero, wherein m + n is from 3 to 100, provided that, when n is finite, m/n is from 5 to 20 and R is preferably -CF3, while when n is zero R is preferably -C2F5 or -C3F7;
x = a finite integer, or zero;
y,z = finite integers, such that x+y+z is from 5 to 200, while (x+z)/y is from 5 to 0.5, provided that, when x is zero z/y is from 1 to 0.5 and y+z is from 5 to 200, while X is preferably F, and R" = L;
L = a group Y-Z, where
Y = -CH20-, -CH20CH2-, -CF2-, or -CF20-;
Z = an organic, non-aromatic, non-fluorinated radical, free from activated hydrogen atoms, containing two or more electron-doublet-donor heteroatoms, or an aromatic radical, either or not containing heteroatoms, capable of giving rise to coordinative bonds or to charge-transfer bonds, thus causing various kinds of adsorption phenomena on metallic polymeric or ceramic surfaces.

R = -CF3、-C2Fs 或 -C3F7
X = F 或 -CF3
R" = F -CF3,或 -C2F5;
m = 3 到 100 之间的整数;
n = 有限整数,或零,其中 m + n 为 3 至 100,但当 n 为有限整数时,m/n 为 5 至 20,R 最好为-CF3,而当 n 为零时,R 最好为-C2F5 或-C3F7;
x = 有限整数,或零;
y,z = 有限整数,如 x+y+z 为 5 至 200,而 (x+z)/y 为 5 至 0.5,条件是,当 x 为零时,z/y 为 1 至 0.5,y+z 为 5 至 200,而 X 最好是 F,R" = L;
