Abstract

Macromonomers capable of both physical crosslinking and chemical crosslinking. The combination of chemical crosslinking and physical crosslinking provides the ability to generate rapidly gelling hydrogels for many different applications. Moreover, the macromonomers may incorporate functional groups that allow for two different gelation mechanisms—thermal gelation and ionic gelation—further improving mechanical stability of hydrogels formed from the disclosed macromonomers.
