| titleOfInvention |
Powdered cationic polyelectrolytes, based on acrylamide and quaternized or salified dimethyl-aminoethyl acrylate, process for producing them |
| abstract |
Cationic polyelectrolytes in water-soluble powder form, applicable to the flocculation of municipal sludge comprise copolymers of acrylamide and of quaternized or salified dimethylamino-ethyl acrylate, containing in molar proportions 10 to 50% of cationic units distributed regularly along the copolymer chains. They have an intrinsic viscosity higher than 6 and a measured cationicity higher than 90% of the theoretical cationicity. |
