The title complexes comprise (a) a poly-2-oxazoline or poly-2-oxazine, such as the homopolymers of polymerized 2-ethyl-2-oxazoline or 2-ethyl-2-oxazine, and (b) IBrCl- or polyhalide anion of the formula (XY2n)- where X and Y are individually chloride, bromide or iodide, but not both chloride, and n is 1, 2 or 3, and an independently supplied cation selected from the group consisting of alkali metals, alkaline earth metals, hydrogen and mixtures thereof. These complexes are readily prepared in either an aqueous or anhydrous environment at room temperature and are significantly more stable than either complexes of polyoxazolines or polyoxazines and halogen or interhalogen; or complexes of polyvinylpyrrolidone and polyhalide anions. |
