Abstract
Substituted 5- to 6-membered heterocyclic amine monomers are provided. Methods of making the same, wherein a polymer is heated under vacuum to crack it into monomeric units and the aceto moiety is converted to a selected moiety, are provided. Monomers including unhalogenated or halogenated hydantoins, triazine diones, imidazolidinones, or pyrimidinones are provided. The heterocyclic amine monomers can be utilized to form biocidal N-halamine polymers which are stable, insoluble biocides which release only small amounts of free halogen and other impurities.
