Abstract Polyacrylamide (PAM) was synthesized by using reverse phase emulsion polymerization. The effects of reaction conditions on the limiting viscosity number of PAM and the water light transmittance of flocculated coal slurry were studied. The optimum reaction conditions were determined by experiments as follows: the dosage of initiator 0.1%, the content of monomer 26%—29%, reaction temperature 35 ℃, the content of accessory ingredient carbamide 5%, the volume ratio of oil to water 1.5∶1. Under such reaction conditions, the limiting viscosity number of PAM was 1 400 mL/g, the light transmittance of flocculated coal slurry reached 95%, which showed the PAM had very well flocculation functions.
