Functionalized polymer, rubber composition and pneumatic tire |
| 摘要 |
The present invention is directed to a functionalized elastomer comprising the reaction product of a living anionic elastomeric polymer and a polymerization terminator of formula I;
wherein R1 is C1 to C4 linear or branched alkanediyl;
Z is R2, —OR3, or —R4—X; R2, R3 are independently C1 to C18 linear or branched alkyl; R4 is C1 to C18 alkanediyl;X is halogen or a group of structure II, III, IV, V or VI;
wherein R5, R6, R7, R8, and R9 are independently H or C1 to C8 alkyl; R10 is C2 to C8 alkanediyl; R11 and R12 are independently H, aryl or C1 to C8 alkyl;
Q is N or a group of structure VII;
wherein R13 is C1 to C8 alkyl. |
