| Abstract: | A novel methods of continuous preparation of monodispersed polymer particles by using microwave radiation and emulsifer free emulsion polymerization is reported.Moreover,the way is convenient, low energy consume and enviroment friendly.In the experiment, entering feed and exceeding feed can be processed at one time , which make the preparation of monodispersed polymer particles industrialized by any possibility. We have prepared the polymer particles of PMMA and PSt by the method saparately, and the experiment results indicated that these polymer particles are monodispersed (by LLS and TEM). By the way, the effects of monomer concentration and initiator concentration on particle size of polymer (PMMA or PSt) are investigated. At last, the experiment is explained by the different nucleation mechanism of emulsifer free emulsion polymerization of MMA and Styrene under microwave radiation. |
