ChemInform Abstract

Cresols are polymerized by an enzymatic oxidative process in aqueous organic or in a reverse micellar solution by employing a peroxidase catalyst derived from horseradish and soybean. The formed polymers are partly soluble in DMF and DMSO and insoluble in H2O and other common organic solvents. The molecular weight of the DMF-soluble part is . apprx.5000. The polymers have no clear glases transition and melting points and exhibit relatively high thermal stability. The polymers from o- and m-cresol are of higher stability than those from p-cresol.
