摘要： A hydrogenated functionalized polymer comprises a functionalized polydiene, which selectively hydrogenated to a predetermined level of saturation along at least a polydiene portion of the functionalized polydiene. The functionalized polydiene is a reaction product of a living anionic elastomer initiated with a functionalized lithium initiator of the formula (I)
wherein n is 1 to 8; and R1, R2, and R3 are independently selected from alkyl groups containing from 1 to 8 carbon atoms. The polymer is also a reaction product of (1) the living anionic elastomer and a functional terminator, both of which produce a polymer having chains of the structural formula (II)
Each Polydiene represents polymer chains comprising at least one partially or fully hydrogenated diene monomer. R1 and R2 independently represent alkyl groups containing 1 to 8 carbon atoms.-

摘要： A hydrogenated functionalized polymer comprises a functionalized polydiene that is selectively hydrogenated to achieve a predetermined level of saturation along at least the polydiene portion of the functionalized polydiene. The functionalized polydiene is a reaction product of a living anionic elastomeric polymer and a polymerization terminator of formula I
In one embodiment, R1, R2 and R3 are independently C1 to C8 alkyl or C1 to C8 alkoxy, with the proviso that at least two of R1, R2 and R3 are C1 to C8 alkoxy; R4 is C1 to C8 alkyl; Si is silicon; S is sulfur; and Z is R5 or of formula II
where R5 is alkyl, aryl, alkylaryl or arylalkyl.-
