Abstract This chapter deals with the peroxidase-catalyzed polymerization of phenol and
its derivatives. Such a polymerization needs an oxidation reagent, normally hydrogen
peroxide. Since this type of polymerization is believed to be a potential environmen-
tally friendly alternative process for the production of phenol–formaldehyde resins, it has
been investigated thoroughly by many research groups. Typical re
