N—Ar
1
—NH—CH
2
—CH(OH)—(CH

—[X]
n
—HN—Ar

in which X represents the string:
—HN—Ar

and in which n represents an integer equal to zero or different from zero;
m, which are identical or different, represent an integer within a range from 1 to 10; Z
1
and Z
2
, which are identical or different, represent a divalent bonding group comprising from 1 to 30 carbon atoms; and Ar
1
, Ar
2
and Ar
3
, which are identical or different, each represent a phenylene group, at least one of these phenylene groups bearing one, two, three or four groups of formula —S
x
—R in which “x” is an integer from 1 to 8 and R represents hydrogen or a hydrocarbon group which can comprise a heteroatom and which comprises from 1 to 10 carbon atoms.
