Abstract
Acacia gum (AG) was grafted with polyacrylamides with different catonic ratios obtained by using different amounts of acrylamide (AM) and methacrylatoethyl trimethyl ammonium chloride (DMC (cationic monomer)). The thermal properties of these grafted products were investigated by differential scanning calorimetry (DSC) and thermogravimetric (TGA) analyses. The formation of grafted products was confirmed by FTIR spectroscopy and thermal analysis. The effects of different cationic ratios of polyacrylamide on flocculation were evaluated. Flocculation performance was evaluated in kaolin suspension.
