The coal-water slurry dispersant was prepared by 2-acrylamide-2-methylpro panesulfonic acid(AMPS),acrylic acid(AA) and itaconic acid(IA)(terpolymer).Through the viscosity curves which was characteristic of this coal dispersant,the best synthetic conditions had been determined: monomer ratio:m(AMPS)∶m(AA)∶m(IA)=3.8∶1∶1,reaction temperature 85℃,the adding amount of initiator and sodium hypophosphite was 5% and 10% amount of monomers,respectively.The copolymer was characterized and analyzed by FT-IR,XRD and GPC.The results showed sulfonic group and carboxylic acid group were successfully introduced into copolymer and the dispersant,and the GPC showed the weight average molecular weight of about 1.6×10^4,polydispersity was 3.41.
