Abstract
A covalently crosslinked absorbent graft copolymer is provided comprised of a water-soluble base monomer and a water-soluble or water-dispersible macromer. In a preferred embodiment, the water-soluble base monomer comprises a carboxylic hydroxyalkyl ester monomer and the water-soluble macromer comprises an ethoxylated or propoxylated hydroxyalkyl (meth)acrylate. The covalently crosslinked absorbent graft copolymer exhibits desirable water absorbency and water vapor transmission rates and may be used in a variety of medical applications such as a wound dressing, medical adhesive or biomedical electrode.
