AMPS(2-acrylamido-2-methylpropanesulfonicacid)/MMA(methyl methacrylate) copolymer microspheres were prepared without initiator or emulsifier by ultrasonic irradiation emulsifier-free emulsion polymerization.The samples were characterized and tested by FTIR,TGA-DSC,TEM and Zeta-sizer,and the reaction mechanism of the copolymerization was studied as well.The results show that the monomer conversion was 83% in 75 minutes at a power output of 200 W and 45 ℃.The microspheres possess a good dispersity,a uniform size with a diameter of 0.77 μm and a T_g of 120 ℃.
