Abstract
The present invention relates to a process for preparing phenolic polymers utilizing Coprinus cinereus peroxidase. More particularly, the present invention relates to a process for preparing phenolic polymers by polymerizing phenolic monomers with Coprinus cinereus peroxidase instead of using typical peroxidase which essentially requires the use of toxic formalin or peroxidase of plant origin which is very costly and easily deactivated by hydrogen peroxide in the polymerization of phenolic monomers, wherein the polymerization is conducted in the presence of a polar organic solvent under mild reaction conditions of atmospheric temperature and pressure to economically produce desired phenolic polymers having excellent water and chemical resistances with high yield.
