제목 | Synthesis of a new crosslinkable polycardol from a renewable resource using fungal peroxidase from Coprinus cinerius |
초록 | Commercially available technical cashew nut shell liquid (CNSL) contains mainly cardanol and cardol. Cardol is a resorcinol derivative from CNSL mainly having a C15 unsaturated hydrocarbon chain with 1 to 3 double bonds at a meta position. Industrial applications of the CNSL-based products are numerous, including brake linings, paints and primers, foundry chemicals, lacquers, cements, and specialty coating. The cardol with resorcinol structure may be useful to produce new application materials to give thermal stability and high hardness compared to cardanol. In the present study, we examined the potential use of Coprinus peroxidase(Cip) for the industrial oxidative polymerization of cardol in water-organic solvent mixture. The effects of reaction conditions on the Cip-catalyzed polymerization of cardol were also investigated. Among the organic solvents used, tert-butanol gave the highest yield of polymer. The control of H2O2 concentration was very sensitive to maintain peroxidase activity and to increase the polymer yield and molecular weight during the enzymatic polymerization of cardol. Thermal analysis shows that polycardol has relatively high thermal stability. Reference 1. R. Ikeda, H. Tanaka ,H. Uyama , S. Kobayashi, Polymer J., 32-7, 589(2000) 2. Y. H. Kim. K. W. Won, J. M.
