The cellulosic part of rice straw was modified to develop N-halamine derivatives for disinfection. The process involved cross-linking of the cellulosic material with amino/amide/imide containing compounds; cyclic and acyclic. The structures of the pr

An N-Halamine biocidal polymer was prepared by co-polymerizing toluene-2,6-diisocyanate with a new heterocyclic uramil-based azo-monomer, followed by halogenation. The mode of action of N-halamine polymers on bacteria was investigated and halogenatio

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

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 poly
