Abstract: Ortho-imine functionalized oligophenol was synthesized via enzymatic polymerization of 2-((4- nitrophenylimino)methyl)phenol (NPIMP). Enzymatic polymerization was catalyzed by Horseradish peroxidase (HRP) enzyme and hydrogen peroxide (H2O2) oxidizer yielded oligophenol with imine functionality on the side-chain.Effects of various factors including reaction pH, temperature and solvent…
