| abstract |
The invention relates to terpolymers and their use, said terpolymers comprising one or more nonionic monomers, one or more anionic monomers and one or more cationic monomers. These terpolymers and the compositions containing them can be used as flocculants, for example, to treat residues such as oil sands residues, to facilitate the separation of solids-liquids, for example, in order to efficiently recycle water and / or reduce the volume of residues that can be transferred to a tailings pond and / or to a specific disposal area. |
