A novel biocidal styrenetriazinedione polymer

Polymer, 1996
Abstract Commercial polystyrene has been modified by chemically attaching 6-methyl-1,3,5-triazine-2,4-dione moieties to it in the para position of the aromatic rings. Chlorination of this novel polymer in aqueous base yielded poly(1,3,5-trichloro-6-methyl-6-(4′-vinylphenyl)-1,3,5-triazine-2,4-dione) which functioned as a biocide against the ...

Biocidal polymers active by contact. V. Synthesis of polysiloxanes with biocidal activity

Journal of Applied Polymer Science, 2000
Polysiloxanes with 3-(alkyldimethylammonio)propyl pendant groups were synthesized by quaternization of n-octyldimethylamine or n-dodecyldimethylamine with linear polysiloxanes containing 3-chloropropyl groups and/or 3-bromopropyl groups attached to silicon atoms.

Biocidal polymers active by contact. III. Ageing of biocidal polyurethane coatings in water

Journal of Applied Polymer Science, 1993
AbstractPolyurethane 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, 2010
AbstractSilver 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

2018
The 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.

Disinfection of Water by N-Halamine Biocidal Polymers

Industrial & Engineering Chemistry Research, 1995
Two novel polymers have been tested in a filter application for biocidal efficacy for flowing aqueous solutions of microorganisms. A laboratory water pump was employed in the experiments to provide contact times on the order of 1-2 s/mL. The two polymers are N-chlorinated and N-brominated derivatives of a polystyrene hydantoin.

A new cyclic N-halamine biocidal polymer

Industrial & Engineering Chemistry Research, 1994
A 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, 1990
Abstract 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

2016
Biocide 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 ...
