Patent number: 6548054Abstract: Method for preparing biocidal halogenated polystyrene hydantoins. The biocidal polymers poly-1,3-dichloro-5-methyl-5-(4′-vinylphenyl)hydantoin, poly-1,3-dibromo-5-methyl-5-(4′-vinylphenyl)hydantoin, and their monohalogenated alkali metal salts and protonated derivatives have been prepared as porous beads by use of highly crosslinked polystyrene beads as starting materials. The porous beads will be useful in water and air disinfection applications when employed in cartridge filters and carafes (for water), as well as for controlling noxious odor when mixed with absorbent materials in items such as disposable diapers, incontinence pads, bandages, sanitary napkins, pantiliners, mattress covers, shoe inserts, sponges, animal litter, carpets, fabrics, and air filters or the like.Type: GrantFiled: September 6, 2001Date of Patent: April 15, 2003Assignee: Auburn UniversityInventors: Shelby D.

Publication number: 20030064051Abstract: N-halamine biocidal materials and coatings are provided. Monomeric oxazolidinones or hydantoins are homopolymerized or copolymerized with other monomers so as to produce materials or coatings, which upon exposure to solutions of chlorine or bromine become biocidal.

Publication number: 20030064645Abstract: Biocidal polyester fabrics, fibers and other materials, and methods of preparation. Heterocyclic N-halamine precursor moieties are covalently linked to the polyester material. The fabrics or fibers obtain antimicrobial activity after washing with a source of oxidative halogen such as a chlorine bleach by conversion of the precursor moieties into N-halamine functionalities. The antimicrobial activity can be repeatedly regenerated by further washing with aqueous oxidative halogen. The biocidal polyester fabrics, fibers, and other materials will be effective in reducing, or eliminating entirely, pathogenic and odor-causing microorganisms.Type: ApplicationFiled: May 25, 2001Publication date: April 3, 2003Applicant: Auburn UniversityInventors: Shelby D.
