Abstract
A sulphur-comprising polyaromatic polyamine compound can be used as a monomer or prepolymer, when n is different from zero, in the synthesis of polyurea. The compound corresponds to the formula (I):HN—Ar—NH—CH—CH(OH)—(CH)—O—Z—O—(CH)—CH(OH)—CH—[X]—HN—Ar—NHin which X represents the string:—HN—Ar—NH—(CH)—CH(OH)—(CH)—O—Z—O—(CH)—CH(OH)—(CH)—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; Zand Z, which are identical or different, represent a divalent bonding group comprising from 1 to 30 carbon atoms; and Ar, Arand Ar, 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—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.
