Claim 6:
7. A modified conjugated diene-based polymer of formula (3):, wherein
R1 and R2 are independently a hydrogen atom or a C1 to C8 hydrocarbyl group, or R1 and R2 taken together are a C5 to C8 ring together with the carbon atom to which R1 and R2 bond, R1 and R2 not simultaneously being a hydrogen atom,
R5 and R6 are independently a hydrogen atom or a C1 to C8 hydrocarbyl group, or R5 and R6 taken together are a C5 to C8 ring together with the carbon atom to which R5 and R6 bond, R5 and R6 not simultaneously being a hydrogen atom,
R3 and R4 are independently a C1 to C6 hydrocarbylene group,
R7 is a C1 to C10 hydrocarbylene group,
Poly is an optionally modified conjugated diene-based polymer chain,
Z1 is a C1 to C4 hydrocarbyloxy group or an optionally modified conjugated diene-based polymer chain,
Z2 and Z3 are independently a C1 to C4 hydrocarbyl group, a C1 to C4 hydrocarbyloxy group, or an optionally modified conjugated diene-based polymer chain,
m is an integer in a range of from 1 to 3, and when m is 2 or 3, a plurality of groups R7, a plurality of R3, R7, Z1, Z2, or Z3 are identical to or different from one another.
