2,6-Xylenol was oxidatively polymerized by Cu-poly (vinylpyridine) (PVP) complex or Cu-partially-quaternized PVP (QPVP) complex in a homogeneous dimethylsulfoxide solution, and the mechanism of the catalysis of the polymeric Cu complexes was discussed. The catalytic activity of the Cu-QPVP complex exhibited a maximum in the region where the percentage of quaternization of QPVP was 20-50% and tended to increase with the degree of polymerization of QPVP. Considering through the kinetic constants of the polymerization, the neutral salt effect, and the influence of the monomer species, it was cleared that the higher activity of the Cu-QPVP catalyst was attributed to the electrostatic interaction between the QPVP complex and the anionic monomer. It is considered that the frequency factor of the dissociation step of the activated monomer increases because of the high density of cupric ion in the polymer complex.
