CiP(Coprinus cinereus peroxidase) catalyzing a phenolic derivates such as m-cresol, p-cresol, bisphenol A can produce a potential applicable materials in electrooptics. For application to the industry, to know the properties of polymer and its behavior control is significantly import. We investigate in the polymerization of m-cresol and p-cresol using CiP as catalyst effects of organic solvent composition, yield, solubility and molecular weight. It has a difference with solubility, ratio of phenylene bridge, yield to perform m-cresol and p-cresol synthesized in the same conditions(pH, solvent composition, temperature). Unexpectedly, increasing of p-cresol ratio causes the decreasing of yield, molecular weight and ratio of oxyphenylen bridge. By the contrast, increasing of m-cresol causes the increasing of yield, molecular weight and ratio of oxyphenylen bridge, however it has a increasing insoluble product. To improve their a individual defect is overcome by copolymerization of m-cresol and p-cresol ,using their complementary property, from the appropriable water miscible organic solvent and buffer.
