The invention concerns the use of at least a water soluble polymer obtained by copolymerising: at least an ethylenically unsaturated monomer (a) having a group capable of being protonized in the medium where it is to be used with: at least an ethylenically unsaturated monomer (b) bearing an acid character function copolymerisable with (a) and capable of being negatively ionized in the medium where it is to be used; and optionally at least an ethylenically unsaturated neutrally charged monomer (c), preferably bearing one or several hydrophilic groups, copolymerisable with (a) and (b), to improve the biocidal efficiency of biocidal compositions comprising a cationic biocidal compound.
Cette invention concerne l'utilisation d'au moins un polymère hydrosoluble obtenu par copolymérisation: d'au moins un monomère (a) à insaturation éthylénique possédant un groupe susceptible de se protoner dans le milieu d'application avec au moins un monomère à insaturation éthylénique (b) portant une fonction à caractère acide copolymérisable avec (a) et susceptible de s'ioniser négativement dans le milieu d'application; et éventuellement au moins un monomère à insaturation éthylénique (c) de charge neutre, de préférence portant un ou plusieurs groupes hydrophiles, copolymérisables avec (a) et (b); pour améliorer l'efficacité biocide de compositions biocides comprenant un composé biocide cationique.
