Abstract
Biodegradable biocompatible hydrogels based on poly(vinyl alcohol) and methods for their preparation. The methods for preparation of the hydrogels involve the use of prepolymers. The prepolymers have a PVA backbone and pendant chains that include a polymerizable group. In one embodiment, the pendant chains also include a biodegradable region. In another embodiment, biodegradable regions are incorporated into the hydrogel during its formation.
