Abstract

An increasing number of novel materials are synthesized from polyfunctional precursors. These materials included chiral polymers, photo-optical materials (e.g., to provide control of refractive index), and biodegradable/biocompatible polymers. Highly selective (e.g., regio-, stereo-, and chemo-) syntheses are often required for suitable polymeric properties. Specific examples of this requirement are the synthesis of water-absorbent, biocompatible/biodegradable polymers from sugars and the synthesis of modified lignins with free phenolics to produce reactive phenolic resins. In both instances, the biological reactant is multifunctional and are well-suited for enzymic modification. Chemoenzymatic synthesis represents a significant advantage over either purely chemical approaches (enhanced regioselectivity) and purely enzymatic routes (greater speed and, in the case of poly(sucrose acrylate), substantially higher molecular weights). Hydrogels prepared by this approach contain extremely high equilibrium water contents and are predominantly composed of sugars which are biodegradable and biocompatible.
