Electropolymerization of coniferyl alcohol

Journal of Wood Science, 2009
Electropolymerization of coniferyl alcohol was carried out in an aqueous system (0.2 M NaOH) and in an organic solvent system [CH2Cl2/methanol (4:1 v/v) in the presence of 0.2 M LiClO4] to produce a dehydrogenation polymer (DHP) - artificial lignin. In both systems, the polymerization of coniferyl alcohol was visually confi rmed. In the aqueous system,
