New N-Halamine Biocidal Polymers
Journal of Bioactive and Compatible Polymers, 1998A new series of N-halamine polymers has been synthesized and tested in granular form, on glass and as fiber substrates for efficacy at inactivating bacteria. Copolymers and grafted copolymers were prepared with 4-(alkyl acryloxymethyl)-4-ethyl-2-oxazolidinones and commercial monomers or polymers.

Biocidal polymers active by contact. III. Ageing of biocidal polyurethane coatings in water
Journal of Applied Polymer Science, 1993AbstractPolyurethane coatings prepared from hydroxytelechelic polybutadiene with pendant qua‐ternary ammonium salts (QAS) are able to kill microorganisms, these biocidal polymers were submitted to various ageing conditions. The activity remained constant after exposure to a very high number of bacteria (Escherichia coli).

Mechanically Switchable Biocide Plasma‐Polymer Coatings for Biomaterials
Advanced Engineering Materials, 2010AbstractSilver nanoparticles are enclosed between two plasma‐polymer layers. We show that the second cross‐linked plasma‐polymer network acts as a barrier and significantly reduces the delivery of the silver nanoparticles into a surrounding aqueous environment.

Biocidal Activity of Phthalocyanine–Polymer Complexes
2018The aggregation behavior of iron, manganese, and magnesium phthalocyanine (Pc) with poly-N-vinylpyrrolidone and polyethylene glycol was considered in this chapter. Biocidal activity of iron and manganese Pc complexes with polymer in relation to nine cultures of microorganisms was determined.

Synthesis of Novel N-Halamine Biocidal Polymers
Journal of Bioactive and Compatible Polymers, 1999Two new water-insoluble polymeric biocides have been synthesized: poly[3-chloro-2,2,5,5-tetramethyl-1-(4'-vinylbenzyl)imidazolidin-4-one] (Poly-p-VBD-Cl) and poly[acrylonitrile-co-(1,3-dichloro-5-methyl-5-(4'-vinylbenzyl)barbituric acid)] (Poly-AN-Barb-Cl).

A new cyclic N-halamine biocidal polymer
Industrial & Engineering Chemistry Research, 1994A new biocidal polymer is described. The compound, poly(1,3-dichloro-5-methyl-5-(4'-vinylphenyl)-hydantoin), is prepared in a three-step synthesis from commercial polystyrene. It is insoluble in water and common organic solvents and acts as a contact biocide for contanainated water or air flowed through it.

The biodeterioration of polymer emulsions and its prevention with biocides
International Biodeterioration, 1990Abstract Polymer emulsions, also referred to as polymer dispersions, latices, latex emulsions or latex dispersions are used in an increasingly wide variety of applications including production of emulsion paints, adhesives, paper and textile coatings, non-woven fabrics and carpet-backing compounds.

Efeects of Biocidal Regulations on Polymer Producers
2016Biocide actives can be hazardous for both human health and environment so their amount of usage is limited by particular regulations. Recently second revision of EC 1272/2008 GHS, also known as CLP regulation in European Union is announced. The usage limits of biocide actives which may cause allergic reactions, have been lowered with the revision in ...

Protection Against Pathogens via Biocidal Polymers
2005Abstract : The goal for this project was to establish feasibility for a surface modifying additive concept whereby the surface of coatings could be made antimicrobial. Proof of principle was established via the synthesis and testing of a generation 1 (Gen- 1) polyurethane antimicrobial surface modifying additive that killed challenges of P. aeruginosa (
