Abstract

The invention describes families of compounds that utilize multihydroxyl phenyl groups to provide adhesive properties. Selection of the multihydroxy phenyl group along with linkers or linking groups and the linkages between the linkers or linking groups with polyalkylene oxides, provides materials that can be engineered to afford controllable curing time, biodegradation and/or swelling.
