Reactive and Functional Polymers, 2008 Novel N-halamine biocidal polymers were prepared by co-polymerizing a heterocyclic ring-based monomer with tolylene-2,6-diisocyanate and toluene-2,4-diisocyanate. The resulting polyurethanes were halogenated; chlorinated, brominated or iodinated. The rate of bacterial killing by the halogenated derivatives was determined both with and without halogen ...

Reactive and Functional Polymers, 2008 Biocidal polymers were prepared by reacting uramil with polyacrylonitrile and polyethylacrylate, and also by co-polymerizing heterocyclic monomers based on uramil azo-dyes with tolylene-2,6-diisocyanate and toluene-2,4-diisocyanate. The prepared polymers were converted to their quaternary salts and N-halamine forms.

Biocidal Polymers: A Mechanistic Overview [PDF]
Polymer Reviews, 2016 Bacterial fouling on surfaces is considered a major problem in modern society. Conventional methods to prevent biofilm formation often have little effect and may induce further contamination. In response to this challenge, biocidal polymers have been designed and applied as an alternative approach to kill or inhibit bacteria and prevent the formation ...
