Conventional chloromethylation

paraformaldehyde/hydrogen chloride in acetic acid medium

was applied to 1

2- dimethoxybenzene.Chloroform-soluble poly（3

4-dimethoxy-o-tolylene）was obtained with an intrinsic viscosity of 0.034 dL g

-1

.The polymer was evaluated as a condensation redox polymer precursor formed by a Friedel-Crafts reaction. Cleavage of the methoxy groups present in this polymer resulted in poly（3

4-dihydroxy-o-tolylene）which manifested a great air-oxidation resistance.The redox property of the latter polymer was found to be 1017 mV by potentiometric titration with 0.05 N ceric ammonium nitrate at 25℃.This midpotential was compared to that of catechol

a monomeric analogue

under the same titration conditions.
