The present invention relates to a cleaning implement comprising a modified open-cell foam with a density in the range from 5 to 1,000 kg/m3 and with an average pore diameter in the range from 1 µm to 1 mm, comprising an amount in the range from 1 to 2,500% by weight, based on the weight of the unmodified open-cell foam, of at least one water-insoluble polymer (b), selected from polystyrene, styrene copolymers, polybutadiene, butadiene copolymers, polyvinylesters, polyvinylethers, copolymers from (meth) acrylic acid with at least one (meth)acrylate, and polyurethanes, with the proviso that styrene- acrylonitrile-C1-C10-alkyl (meth)acrylate terpolymers, styrene-butadiene-n- butyl acrylate terpolymers, and styrene-maleic anhydride copolymers are excluded.

Cette invention concerne un outil de nettoyage comprenant une mousse à alvéoles ouvertes modifiée présentant une densité comprise entre 5 et 1,000 kg/m3 et un diamètre moyen des pores compris entre 1 µm et 1 mm; la mousse à alvéoles ouvertes modifiée comprenant de 1 à 2500% en poids, sur la base de son propre poids, d'au moins un polymère non soluble dans l'eau (b), choisi dans le groupe comprenant le polystyrène, les copolymères de styrène, le polybutadiène, les copolymères de butadiène, les polyvinylesters, les polyvinyléthers, les copolymères obtenus à partir de l'acide methacrylique avec au moins un methacrylate, et les polyuréthanes, pour autant que les terpolymères styrène-acrylonitrile-C1-C10-alkyle méthacrylate, les terpolymères styrène-butadiène-n-butyl acrylate, et les copolymères styrène-anhydride maléique soient exclus.
