The preparation of polyepichlorohydrin substituted by imidazole from polyepiehlo-rohydrin and lithium imidazolide in aprotic dimethyl sulfoxide was proved successful. These polymeric ligands coordinate with CuCl2 in alcoholic solution rapidly and tend to form complexes with Im/Cu molar ratio equaling to 4. All macromolecular complexes obtained are insoluble in coommn solvents

and in the presence of them

the oxidative coupling of 2

6-dimethylphenol in dichlorobenzen-methanol(6.5/1

V/V) shows both "cooperativity"and "substrate inhibition". So

the reaction takes place by a enzyme-like mechanism.
