Enzymatic polymerisation of phenols appeared as a safe alternative to the phenol–formaldehyde process which was questionable in terms of both health and environment impact, and the topic of the polymerisation of phenolics by peroxidases from the polymerist viewpoint has been reviewed in 2006 (Reihmann and Ritter, 2006). The general topic of biocatalysis in polymer chemistry has been addressed in a book published in 2010 (Loos, 2010). Many studies have been directed towards the control of the final size and dispersity of the polymer. The HRP-catalysed oxidative polymerization of phenol in the presence of PEG-derived triblock copolymers has been reported to yield ultrahigh molecular weights (Kim et al., 2008). The formation of a micellar aggregate of the phenol growing polymer and the PEG derivative through hydrogen bonding served as template and maintained the polymer in the aqueous phase which allow to reach a molecular weight up to 106 Da. Polyphenol-graft-polyethylene glycol copolymer could also be obtained from HRP-catalysed phenol polymerisation combined with living anionic polymerisation of ethylene oxide, yielding polymers of 2000–8000 Da (Cui et al., 2010). The resulting copolymer showed improved solubility in solvents such as water, ethanol, and dichloromethane.
