Abstract

Oil sands mining operations in Canada produce large volumes of waste tailings that are difficult to dewater using commercial polyacrylamide-based flocculants. Recently, we have developed a novel hydrolytically-degradable polymer synthesized through micellar radical polymerization of short-chain polyester cationic macromonomers. Poly(PCL₂ChMA), made of polycaprolactone choline iodide ester methacrylate with two polyester units, effectively treated mature fine tailings (MFT) solutions as evaluated by measuring initial settling rate, supernatant turbidity, and capillary suction time (CST) of the sediments^[1].
