Destruction of microorganisms in aqueous systems, involves addition of a water-soluble or -dispersible styrene sulfonic acid (co) polymer as biocide

摘要

Destruction of microorganisms in aqueous systems or in products for aqueous uses involves addition of 0.001-5 wt.% of a biocide comprising a water-soluble or -dispersible polymer containing on a molar basis (a) styrene sulfonic acid (30-100%); (b) an N-vinyllactam and/or N-vinylamine (0-40%); and (c) a further radically-polymerizable monomer (0-30%). An Independent claim is also included for antimicrobial protection of articles by applying the above biocide composition containing water or a mainly water-containing solvent mixture and then removing the water or mainly water-containing solvent mixture.
