Water-soluble poly(methacrylohydrazide)(PMH) was prepared by the hydrazinolysis of polymethylmethacrylate with hydrazine hydrate. The intrinsic viscosity of PMH measured in the range of 1.04-2.03.
Poly (methyl methacrylate-acrylamide)(PMMA-AM) was prepared by copolymerization of acrylamide with methylemethacrylate, The intrinsic viscosity of PMMA-AM measured in the range of 0.54-1.09
The flocculation effect was studided by observing the sedimentation rate, the sedimentation volume and the turbidity of the supernatant liquid of the kaoline suspension.
The flocculation effect of the PMMA-AM was increased with the increase of the increase of the intrinsic viscosity of these polymers
