Functionalized polymer, rubber composition and pneumatic tire |
| abstract |
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 n nwhere n is an integer from 1 to 3;n nX is a tetravalent organic group selected from a hydrocarbyl group of formula C m H 2m-2 where mn nis an integer from 1 to 10, a group of formula IIn n nwhere R 3 is C1 to C10 alkane diyl, and the group of phenyl diyl;n nR 1 and R 2 are independently selected from C1 to C10 alkyl, and a group of formula IIIn n nwhere R 4 , R 5 are independently C1 to C10 alkyl, and R 6 is C1 to C10 alkanediyl;n nor R 1 and R 2 taken together with their common Si atom form a five-membered heterocyclic ring selected from formulas IV and Vn n nwhere R7 is from C1 to C10 alkyl. |
