RUBBER COMPOSITION AND PNEUMATIC TIRE |
| 摘要 |
There is disclosed a vulcanizable rubber composition comprising:
(A) a functionalized elastomer comprising the reaction product of a living anionic elastomeric polymer and
a polymerization terminator of formula I
;;where 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;
(B) a polymeric amine comprising a primary amine functionality; and(C) an aromatic carboxylic acid or aromatic acid anhydride. |
