A stable, mixed form halogenated and/or interhalogenated molecular addition reaction product comprising a copolymer in the form A/B-X, wherein X includes polyvinylpyridine having the cyclic pyridyl functional ring group C5H5N crosslinked with about 2-25% divinylbenzene, and A/B is a combination of halogens and/or interhalogens bonded to the nitrogen atom of the pyridyl functional group of X and selected from the group consisting of I2/ICl, I2/IBr, I2/Br2, I2/BrCl, Br2/BrCl, Br2/ICl, Br2/IBr, BrCl/ICl, BrCl/IBr, ICl/IBr, and mixtures thereof, such that at least about 10% of the pyridyl functional groups are complexed by the combination A/B in proportions such that A to B is present in the molar ratio of from about 0.08 to about 0.92.
