Organosolv lignin was used as a macromolecular initiator for the anionic polymerization of glycidol.  The resulting amphiphilic lignin core hyperbranched polyglycerols were characterized by a series of techniques including NMR, gel permeation chromatography, differential scanning calorimetry, and thermal gravimetric analysis.  The polyglycerol corona was cross-linked using both diisocyanate chemistry and reversible Diels-Alder chemistry.  Thin films of these water insoluble cross-linked materials were studied and the results of will be presented.
