Abstract:
A composition comprising a hydrocarbon polymer derived from at least one olefinically unsaturated hydrocarbon polymer selected from the group consisting of:1) polymers of dienes: (2) copolymers of conjugated dienes with vinyl substituted aromatic compounds; (4) olefin-diene copolymers; and (5) star polymers, having {overscore (M)}n ranging from 20,000 to about 500,000, when the polymer is not a star polymer, and up to about GPC peak molecular weight of 4,000,000 when the polymer is a star polymer, having attached thereto pendant groups Aa and Bb wherein each A is independently selected from members of the group consisting of:groups of the formula wherein R3 is H or hydrocarbyl, R4 is a divalent hydrocarbylene group, n=0 or 1, and each of R9 and R10 is independently H, alkoxyhydrocarbyl, hydroxyhydrocarbyl, hydrocarbyl, aminohydrocarbyl, N-alkoxyalkyl- or hydroxyalkyl-substituted aminohydrocarbyl, or a group of the formula &Parenopenst;Y&Parenclosest;cR11â€”M, wherein each Y is independently a group of the formula each R11 is a divalent hydrocarbyl group, R12 is as defined above for R9 and R10, and M is H, hydrocarbyl, amino, â€”OH, an amide group, an amide-containing group, an acylamino group, an imide group, a heterocyclic group, an imide-containing group, or â€”SRâ€² wherein Râ€² is H or hydrocarbyl, and c is 0 or a number ranging from 1 to about 100, or one of R9 and R10 taken together with the adjacent N constitute a Nâ€”N group; and each B is independently selected from members of the group of formula: wherein each X is independently O, S, or NRb, each Rb is independently H, NH2, hydrocarbyl, hydroxy-hydrocarbyl or aminohydrocarbyl, and each Z is independently a group of the formula in each of R3, R4, and n is as defined hereinabove; Ra is an ethylene group, a propylene group, which groups optionally have hydrocarbyl or hydroxyhydrocarbyl substituents, or wherein J is H, SH, NH2, or OH, and tautomers thereof; the subscript a is 0 or a number ranging from 1 to about 50 and the subscript b is a number ranging from 1 to about 30.
