Halamine precursors

Polymers can be emulsified in water to produce coatings which, once chlorinated, act as contact disinfectants. These coated surfaces efficiently inactivate microbes within relatively brief contact times, i.e., several minutes. Antimicrobial latexes can be formed via the copolymerisation of an N-halamine precursor monomer with other monomers in water, in the presence of a surfactant, or by chemically grafting the N-halamine precursor monomer onto an emulsified polymer backbone, followed by chlorination. 

A great number of biocidal polymers have been prepared using a grafting or coating procedure. N-halamine precursors can be bonded to substrates via different groups.
