Polymer structure of lignophenol I - Structure and function of fractionated lignophenol

Abstract

A polymer structure and function of lignophenol was examined by various structural analysis of lignophenols fractionated with preparative SEC. The base unit of lignophenol is 1,1-bis (aryl) propane-2-O-aryl ether unit in all the molecular weight areas by NMR analysis. But the amounts of combined cresol and phenolic hydroxyl groups were increased with decreasing molecular weight of fractionated lignophenols. The protein-adsorbing capacities and thermoplastic property of fractionated lignophenols differed with the molecular weights.
