Patent ID: 7683111

Claim:
A method of preparing a functionalized polymer, the method comprising: providing a living polymer; reacting the living polymer with a functionalized epoxide compound defined by the formula where R 1 and R 2 are each independently a monovalent organic group, R 3 is a divalent organic group, R 5 , R 6 , and R 7 each independently include a monovalent organic group or a hydrogen atom, θ is a Group 14 element, and λ includes a leaving group or an addition group, to form a precursor including an epoxide group; and reacting the precursor with a diamine to form a polymer including a primary amine group, where the diamine is defined by the formula where R 8 and R 9 each independently include a monovalent organic group or a hydrogen atom, and R 4 includes a divalent organic group or a covalent bond.
