Abstract
A method for preparing a functionalized polymer, the method comprising the steps of: (i) polymerizing monomer with an anionic initiator to form a reactive polymer; and (ii) reacting the reactive polymer with a nitrile compound containing a protected amino group, where the protected amino group is directly attached to a moiety selected from the group consisting of acyclic moieties, heterocyclic moieties, and non-aromatic cyclic moieties.

A method for preparing a functionalized polymer, the method comprising the steps of:
- (i) polymerizing monomer with an anionic initiator to form a reactive polymer;
- and
- (ii) reacting the reactive polymer with a nitrile compound containing a protected amino group, where the protected amino group is directly attached to a moiety selected from the group consisting of acyclic moieties, heterocyclic moieties, and non-aromatic cyclic moieties, where the protected amino group includes a hydrolyzable group.
A method for preparing a functionalized polymer, the method comprising the steps of:
- (i) polymerizing monomer with an anionic initiator to form a reactive polymer;
- and
- (ii) reacting the reactive polymer with a nitrile compound containing a protected amino group defined by the formula I:
- where R1 is a divalent organic group, and R2 and R3 are each independently a monovalent organic group or a hydrolyzable group, or R2 and R3 join to form a divalent organic group, with the proviso that at least one of R2, R3, or the divalent organic group formed by joining R2 and R3 is a hydrolyzable group, and with the further proviso that R1 is an acyclic divalent organic group, a heterocyclic divalent organic group, a non-aromatic cyclic divalent organic group that is devoid of heteroatoms, or a divalent organic group containing an aromatic ring that is devoid of heteroatoms so long as, where R1 is a divalent organic group containing an aromatic ring that is devoid of heteroatoms, the protected amino group is not directly attached to the aromatic ring.
