Synthesis, Characterization, and Flocculation Properties of Branched Cationic Polyacrylamide
24/4/2013 · However, if the concentration of initiators was too high, the intrinsic viscosity of branched cationic polyacrylamide decreased. From Figure 5 , it can also be seen that the intrinsic viscosity rises to the maximum when the concentration of init
[Study on infrared spectroscopy of cationic polyacrylamide initiated by ultraviolet].
Cationic Polyacrylamide P(AM-DAC-BA) was synthesized by UV initiation, with acrylamide (AM), acryloyloxyethyl trimethyl ammonium chloride (DAC), butyl acrylate (BA) as the monomers. P(AM-DAC-BA). UV spectroscopy and infrared spectroscopy were
Preparation of cationic polyacrylamide by aqueous two-phase polymerization
surfactants was weak and its viscosity was large. Until now, there are few works on synthesis of cationic polyacrylamide via aqueous two-phase polymerization without emulsifier. Based on the theory above mentioned, the aqueous two-phase
Dilute solution behaviour of polyacrylamides in aqueous media
1/3/1999 · The viscosity average molecular weights, M v of the polymers were estimated by the Mark–Houwink equation. The literature reported values for k=1.05×10 −4 dl g −1 and α=0.73 for the cationic, k=1.91×10 −4 dl g −1 and α=0.71 for the nonionic polya

flocs. Final sediment height tends to decrease with an increase in polyacrylamide concentration, indicating denser particle associations (face-to-face) and verified with scanning electron microscopy. Viscosity tends to increase as polyacrylamide
Preparation, Characterization, and Sludge Conditioning of Cationic Polyacrylamide Synthesized by a Novel UVA-Initiated System – MDPI
various parameters on intrinsic viscosity, conversion, and dissolvability. Results showed that the best performance was obtained at indices of 0.45 wt‰ redox initiator concentration, 0.2 wt‰ azo initiator concentration, 40.0 wt% cationic monomer
Cationic polymers for reduction of viscosity of a magnesium hydroxide slurry – Calgon Corporation
1. A method for reducing the viscosity of a magnesium hydroxide aqueous slurry which comprises adding 5 pounds/ton or less of a cationic polymer selected from the group consisting of methacryloyloxyethyl trimethyl ammonium methosulfate, vinyl
Dispersion polymerization of anionic polyacrylamide in an aqueous salt medium – Springer
The concentration of salt has a strong effect on the stability of the dispersions. If the concentration is too low, the anionic polyacrylamide particles does not salt out easily from the medium, and solution polymerization takes place. If the co
