Photoinitiated Polymerization of Cationic Acrylamide in Aqueous Solution: Synthesis, Characterization, and Sludge Dewatering Performance

Figure 8

Effect of urea concentration on the molecular weight and dissolving time. (Polymerization conditions: photoinitiators concentration was 0.3%, monomers concentration was 30 wt.%, mass ratio of AM to DAC was 6 : 4, pH value was 5.0, and irradiation time was 60 min.)
