INTRODUCTION Enzymatic polymerization has been extensively developed over the past two decades.1–7 In particular, horseradish peroxidase (HRP) has been used for enzymatic oxidative polymerization of phenolic compounds. Dordick and co-workers8,9 reported HRP-catalyzed polymerization of arbutin, a glucose-bearing phenol derivative. Water-soluble polyarbutins with molecular weight (Mn) in the rang...
