Abstract: In order to explore the mechanism of polymerization between lignin from effluent of pulping process and lignin precursors, the method and mechanism of co-polymerization of coniferin with model compound of β-O-4 type lignin were investigated. The characteristics of polymerization product were analyzed by FT-IR, 13CNMRand gel permeation chromatography(GPC). Polarized microscopy was applied to observe the products. Moreover, GPC was used to determine mumber-average molecular mass (Mn) of the polymerization product. The results showed that coniferin could completely polymerize with model compound of β-O-4 type lignin to form lignin macromolecule. The Mn of the polymerized product was much higher than the starting materials. There was no crystalline starting material in the obtained polymer. These results could be the basis of waste-water treatment using coniferin and enzymes.
