CA 2532953
The invention relates to powdery, water-soluble cationic polymer compositions comprising at least two cationic polymers having a different molecular weight. A first cationic polymer is formed in the presence of a second cationic polymer from monomer constituents in an aqueous solution according to the aqueous gel polymerisation method. The invention also relates to the use of products in solid/liquid separation.
L'invention concerne des compositions de polymères cationiques pulvérulents solubles dans l'eau, lesquelles compositions comprennent au moins deux polymères cationiques de poids moléculaire différent, un premier polymère cationique étant formé en présence d'un deuxième polymère cationique à partir de ses constituants monomères en solution aqueuse après le processus de polymérisation en phase gel aqueuse. Cette invention concerne également l'utilisation de ces produits dans la séparation solide/liquide.
