Abstract:
1. A method for preparing a functionalized polymer, the method comprising the steps of: (i) preparing a living or pseudo-living polymer having a reactive chain end and (ii) reacting the reactive chain end with an imide compound defined by one or more of the formulae: where R 1 and R 2 are each independently a divalent organic group, and R 3 and R 4 are each independently a mono-valent organic group or a hydrolyzable group, or R.sup.3 and R.sup.4 join to form a divalent organic group, where R 1 and R 2 , and R 6 are each independently a divalent organic group, and R 5 and R 7 are each independently a bond or a hydrolyzable group, where R 1 and R 2 are each independently a divalent organic group, and R 8 and R 9 are each independently a hydrogen atom or a mono-valent organic group, or at least one R 8 and at least one R 9 join to form a divalent organic group, and where R 1 and R 2 , and R 6 are each independently a divalent organic group, and R 8 and R 9 are each independently a hydrogen atom or a mono-valent organic group.
