Monodispersed polymethyl metharylate(PMMA) microspheres were synthesized by emulsifier-free emulsion polymerization under the microwave irradiation. 2,2'-Azobis(2-methylpropionamidine)dihydro chloride(AIBA) and potassium persulphate(KPS) were used as cationic and anionic initiators. The effects of initiator, heating ways and monomer concentration on the particle size, uniformity and polymerization rate were discussed. By using AIBA as an initiator, the diameter of particle obtained was smaller than the corresponding polymer particles initiated by KPS, but the polymerization rate was more rapid to give more particles. Increasing the monomer concentration increased the particle diameter but decreased the conversion rate and the number of particles. In comparison with the conventional heating method, microwave irradiation could shorten the polymerization time and give more particles with smaller particle diameter.
