Embodiment Construction

[0033] It should be remembered firstly that a polyurea is a polymer (by definition any homopolymer or copolymer, especially a block copolymer) comprising a plurality of urea linkages (NH-CO-NH-), which are obtained in a known manner From the addition reaction of polyamines having at least two primary amine functions with polyisocyanates (compounds having at least two isocyanate-NCO functions), in particular diisocyanates (in the case of polyureas of the linear type).

[0034] The polyarylamine compounds of the invention thus have essential properties corresponding to the following formula (I):

[0035] (I)

[0036] h 2 N–Ar 1 –NH–CH 2 –CH(OH)–(CH 2 ) m –O–Z 1 –O–(CH 2 ) m –CH(OH)–CH 2 –[X] n –HN–Ar 2 – NH 2

[0037] in:

[0038] -X means chain:

[0039] –HN–Ar 3 –NH–(CH 2 )–CH(OH)–(CH 2 ) m –O–Z 2 –O–(CH 2 ) m –CH(OH)–(CH 2)–

[0040] - "n" is an integer equal to or different from zero;

[0041] - the symbol "m" is an integer ranging from 1 to 10, pref...

Abstract

The invention relates to a sulphuretted polyaromatic polyamine that can be used as a monomer or prepolymer when n is different from zero, for the synthesis of polyurea, said compound satisfying formula (I): H2N−Ar1−NH−CH2−CH(OH)−(CH2)m−O−Z1−O−(CH2)m−CH(OH)−CH2−[X]n−HN−Ar2−NH2 wherein X represents the chain: −HN−Ar3−NH−(CH2)−CH(OH)−(CH2)m−O−Z2−O−(CH2)m−CH(OH)−(CH2)− and wherein: the "n" symbol is a whole number that is equal to zero or different from zero; the "m" symbols are identical or different and are whole numbers between 1 and 10; the symbols Z1 and Z2 are identical or different and are a divalent bond group comprising between 1 and 30 carbon atoms; and Ar1, Ar2 et Ar3 are identical or different and are a phenylene group, at least one of said phenylene groups carrying one, two, three or four groups of formula −Sx−R wherein "x" is a whole number between 1 and 8 and R is hydrogen or a hydrocarbonated group that can comprise a heteroatom and comprises between 1 and 10 carbon atoms.

Description

technical field [0001] The present invention relates to monomers or prepolymers which can be used in the synthesis of polyureas (polymers comprising urea units), which are especially intended for use in adhesive systems for metal or glass with Bonding of rubber, especially intended for use in metal / rubber composites for rubber articles such as tyres. [0002] It relates more particularly to the aforementioned monomers or prepolymers of the sulfur-containing polyarylene type. Background technique [0003] Metal / rubber composites, in particular metal / rubber composites for tires, are well known. They usually consist of a matrix comprising metallic reinforcing elements (or "reinforcements") made of unsaturated rubber (usually a diene rubber) crosslinkable with sulfur, for example from carbon steel obtained threads, films or cords. [0004] Since metal / rubber composites are subjected to extremely high stresses during tire rolling, in particular to repeated actions of compressi...
