<p>A functionalized polymer is provided to ensure reduced hysteresis and improved humidity frictional force while showing reduced tan delta of temperature sweep, strain sweep and Dynastat. A functionalized polymer has a structure of pi-Q-Jm. In the structure, pi is a polymer containing dienemer; J is a functional group including one or more different atoms; M is an integer of 1 to 3; and Q is a linker of -C(Z)NH-R-[NHC(Z)]m-. In the formula of -C(Z)NH-R-[NHC(Z)]m-, Z is independently oxygen or sulfur; and R is substituted or non-substituted aromatic or aliphatic C1-C40 hydrocarbylene group. A method for preparing the functionalized polymer includes the following steps of: reacting end active polymers to polyiso(thio)cyanate; and reacting the polymer whose end is an iso(thio)cyanate functional group to nucleophile containing two or more different atoms selected among O, S, N and Si.</p> |
