Cyclic N-halamine biocidal polymer compounds and methods of using the same wherein the functional groups halogenated hydantoins, triazine diones, imidazolidinones, and pyrimidinones are substituted onto inexpensive polymer units such as polystyrene, polyethylene, and modified polymethacrylamide are provided. These N-halamine polymers are stable, insoluble biocides which release only small amounts of free halogen and other impurities. They will be useful as disinfectants for potable water, swimming pools, hot tubs, industrial water systems, cooling towers, air-conditioning systems, gas streams, paints, oils, ointments, fabrics, sterile bandages, coatings, hard surfaces, liners of containers, and the like.

A biocidal polymer comprising a monomeric repeating unit of one or more structures I, II, III, IV, V, VI, VII, VIII or IX: [Figure] (I) [Figure] (II) [Figure] (III) [Figure] (IV) [Figure] (V) [Figure] (VI) [Figure] (VII) [Figure] (VIII) [Figure] (IX) wherein X, X′and X″are independently chlorine, bromine or hydrogen, provided that at least one of X, X′and X″is chlorine or bromine; R1 is hydrogen or C1 to C4 alkyl; R2 is C1-C4 alkyl, benzyl or C1-C4 alkyl-substituted benzyl; and R3 and R4 are independently C1-C4 alkyl, phenyl, C1-C4 alkyl-substituted phenyl, benzyl or C1-C4 alkyl-substituted benzyl, or R3 and R4 together form a pentamethylene or tetramethylene moiety. A method for disinfecting a habitat for halogen-sensitive microorganisms comprising contacting the habitat with a biocidal amount of a biocidal polymer as claimed in claim 1.
