Abstract

Det er tilveiebrakt vandige dispersjoner av polymerer bestående av (a) en første kationisk vannløselig eller vann-svellbar polymer, og (b) minst en andre vannløselig polymer som er forskjellig fra den første polymer, og (c) et kosmotropt salt, og (d) et chaotropt salt eller anionisk organisk salt, hvor mengdene av (b), (c) og (d) er slik at det fås en homogen blanding i fravær av (b). Det er beskrevet fremgangsmåter for fremstilling av disse vandige dispersjoner, samt fremgangsmåter for anvendelse av dispersjonene ved vannbehandling og awaninng.Aqueous dispersions of polymers consisting of (a) a first cationic water-soluble or water-swellable polymer are provided, and (b) at least a second water-soluble polymer different from the first polymer, and (c) a cosmotropic salt, and (d) ) a chaotropic salt or anionic organic salt, the amounts of (b), (c) and (d) being such that a homogeneous mixture is obtained in the absence of (b). Methods for preparing these aqueous dispersions are disclosed, as well as methods for using the dispersions in water treatment and dewatering.
