New polyurea having recurring structural units of sulfur containing polyaromatic polyamine compound, useful as an adhesion primer for adhering a substrate to an unsaturated rubber, where the substrate is a glass substrate

摘要

Polyurea having recurring structural units of sulfur containing polyaromatic polyamine compound (I), is new. Polyurea having recurring structural units of sulfur containing polyaromatic polyamine compound of formula (HN-Ar1-NH-CH 2-CH(OH)-(CH2) m-O-Z1-O-(CH 2) m-CH(OH)-CH 2-[X] n-HN-Ar2-NH) (I), is new. X : -HN-Ar3-NH-(CH 2)-CH(OH)-(CH 2) m-O-Z2-O-(CH 2) m-CH(OH)-(CH 2)-; Z1, Z2 : a divalent linking group having 1-30C; Ar1-Ar3 : phenylene groups, where at least one of the phenylene groups is substituted with one, two, three or four groups of formula (-Sx-R) (II); R : H or hydrocarbyl containing heteroatom having 1-10C; x : 1-8; n : integer equal to zero or different from zero; and m : 1-10.
