Monodispersed cationic microspheres of polystyrene prepared by dispersion polymerization
WANG ZhanLi;LIU LianYing;DENG JianPing;MA YuHong;YANG WanTai
Cationic microspheres of polystyrene were prepared through dispersion polymerization in methanol with ［2-(methacryloyloxy)ethyl］ trimethylammonium chloride (DMC) as polymeric stabilizer and AIBN as initiator. The polymerization behavior and effects of varying the concentration of stabilizer, monomer and initiator onparticle size and size distribution were studied. By means of SEM, it was shownthat monodispersed microspheres of polystyrene with particle size in the range of 0.98～2.78μm could be obtained.
