摘要：

The hydrophobically modified polyacrylamides (PAM) were synthesized using butyl acrylate (BA) and methyl methacrylate (MMA) as hydrophobic monomers, via water solution free radical copolymerization. The influences of hydrophobic monomer content on the molecular weight, insoluble fraction and dissolution rate of PAM were investigated. The flocculation effects of PAMs for two kinds of tailing slurry with difficult sedimentation feature were also evaluated. The results show that different flocculation effects of hydrophobically modified PAMs can be obtained according to different kinds of tailing slurry.
