Abstract

La présente invention concerne l'utilisation de polymères attirant la saleté, les polymères étant formés à partir de monomères de (méth)acrylate de 2-tert-butylaminoéthyle (tBAEMA). Des lingettes de nettoyage, des garnitures de balai et des substrats similaires sont traités avec les polymères formés pour améliorer la récupération de la saleté sur la surface nettoyée. Les polymères peuvent être incorporés directement dans des substrats non tissés ou ils peuvent être formulés avec une composition de nettoyage destinée à être utilisée avec le substrat. Les polymères attirant la saleté peuvent être utilisés pour nettoyer les surfaces dures, comme les sols, les comptoirs, les toilettes, les fenêtres et les automobiles.
