Abstract

A copolymer comprising an oxygenated polyaromatic alcohol and a poly (alkylene oxide) alkyl ether (meth)acrylate is disclosed, wherein the oxygenated polyaromatic alcohol is preferably lignin or lignin derivative. A hydrogel comprising the copolymer and a cyclic oligosaccharide such as α-cyclodextrin is also disclosed, which can be used in biomedical or personal care industries, for example as a carrier for an active agent.
