Abstract:
A material comprising:at least one azlactone-functional copolymer comprising a plurality of azlactone moieties and a plurality of azlactone functional groups, wherein the copolymer is derived from monomers comprising at least one alkenyl azlactone monomer and at least one hydrophilic or water soluble comonomer; a first crosslinker comprising a first nucleophilic moiety and a second thermally reactive moiety; and optionally, a second crosslinker comprising a first nucleophilic moiety and a second thermally reactive moiety; wherein: a) the first moiety of the first crosslinker is covalently bound to a first azlactone moiety; and b) the second moiety of the first crosslinker is covalently bound to i) a second azlactone moiety or ii) the second moiety of the second crosslinker, with the first moiety of the second crosslinker being bound to the second azlactone moiety; and wherein the material is a crosslinked hydrogel.
