| abstract |
aqueous solution comprising a cationic copolymer and method for making a sheet of paper and / or cardboard and the like. The invention relates to cationic acrylamide copolymers obtained by hofmann rearrangement using alkaline earth alkali and / or hydroxide and alkaline earth alkali and / or hypohalide, and the use of such copolymers primarily as paper strengthening agents and / or coagulants. copolymers are characterized by the desalination coefficient (cd) greater than 0.6, preferably greater than 0.65, advantageously greater than 0.7. |
