A new class of N-halamine polymers has been synthesized. These polymers can
be emulsified in water to produce coatings which, once chlorinated, act as
contact disinfectants. The surfaces inactivate bacterial organisms efficie
ntly, requiring relatively brief contact times of several minutes. The late
xes can be formed by copolymerization of a N-halamine precursor monomer wit
h other monomers in water with the aid of a surfactant, or by chemically gr
afting the N-halamine precursor monomer onto an emulsified polymer backbone
, followed by chlorination. (C) 1998 Elsevier Science Ltd. All rights reser
