Preparation and Characterization of Monodispersed Cationic Polystyrene Microspheres
摘要
Abstract
The monodispersed cationic polystyrene ( PS) microspheres were prepared through dispersion polymerization. The effects of dosages of styrene as monomer, azodiisobutyronitrile( AIBN) as initiator, polyvinylpyrrolidone ( PVP) as disperser and methacryloyloxyethyl trimethylammonium chloride (DMC) as comonomer, and the composition of the reaction media on the cationic PS microsphere size and the size distribution were studied. The structure, particle size distribution and zeta potential of the cationic PS microspheres were characterized by means of FTIR, NMR, FESEM, Zeta potential instrument and Laser Particle Size Analyzer. The results showed that the average size of the cationic PS microspheres was 1.38 μm, its dispersion coefficient was 0.005 and the zeta potential was about +40 mV under the conditions of 10% (w) styrene, 0.2% (w) AIBN, 1.5%(iv) PVP, 0.3% (w) DMC (based on the total mass of the reaction system), temperature of 70 ℃ and volume ratio of ethanol to H2O of 9.关键词
