4-Vinyl pyridine-N-vinyl pyrrolidone copolymers having various copolymer compositions and composition distribution were prepared. The latter was estimated by means of Spinner's equation. The copolymer prepared during the early stage of copolymerization was a random like copolymer, and the polymer polymerized completely was a blend like copolymer. Cu(II) complexes of the prepared copolymers had sufficient catalytic activity for the oxidation of hydroquinone, depending upon their composition distribution and the composition. The Cu(II) complex of the random like copolymer showed a higher catalytic activity than that of the blend like copolymer, even if the copolymers had a similar composition.
