A method for preparing a functionalized polymer, the method comprising the step of reacting a reactive polymer with a functionalizing agent defined by formula I or formula II: n n n n n n n n n n or combinations thereof, where R 1 , R 2 , and R 3 are each independently a divalent organic group, R 4 and R 5 are each independently a monovalent organic group, a is an integer from 0 to 1, x is an integer from 0 to 2, y is an integer from 1 to 3, x+y=3, and γ is a protected amino group. |
