Abstract
The present invention provides alkoxylated polymers. The alkoxylated polymers have two or more alkoxylated sites. The alkoxylated polymers can comprise any monomers and/or oligomers that contain one or more functional groups with an active hydrogen. The alkoxylated polymers are useful in any application for which polymers are generally used. For example, the alkoxylated polymers are useful as additives in ink and coating compositions.
Claims29
An ink or coating composition comprising an alkoxylated polymer, wherein the alkoxylated polymer comprises:
- (a) a backbone with one or more alkoxylated sites;
- (b) terminal ends each of which is a site comprising a functional polar group with an active hydrogen;
- and
- (c) one or more polyfunctional monomers and/or oligomers having two or more functional polar groups with an active hydrogen or mixtures thereof;
- wherein the alkoxylated polymer is present in an amount of 0.1 wt % to 3 wt %;
- wherein the alkoxylated polymer is selected from the group consisting of polyester, polyacrylic, and polyamide;
- and
- wherein the ink or coating composition is solvent-based or water-based, and comprises water, one or more organic solvents, or combinations thereof.
