Abstract
A lactam-functionalized polymer is disclosed. The lactam-functionalized polymer includes lactam-functionalized polyacetal polyether, polyhemiaminal polyether or polyaminal polyether. The applications of the lactam-functionalized polymer are also disclosed.
Claims20
A lactam-functionalized polymer comprising:
- a polymer backbone and at least one lactam-containing moiety attached to the polymer backbone or pendant on the polymer backbone, wherein the polymer backbone is selected from the group consisting of polyacetal polyether, polyhemiaminal polyether, polyaminal polyether, and combinations thereof.
A method for preparing a lactam-functionalized polymer comprising:
- 1) reacting a hydroxyl polyether or hydroxyl polyetheramine with a gem-dihalide to form a polymer backbone;
- and
- 2) reacting the polymer backbone with at least one compound comprising at least one lactam moiety to form the lactam-functionalized polymer.
