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.
Claims22
A lactam-functionalized polymer comprising:
- a polymer backbone and at least one lactam-containing moiety attached to 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.
