【摘要】 采用乳液种子生长法设计生长500-600nm范围的单分散聚苯乙烯微球,研究了种子生长法中新核产生的条件,当乳化剂对苯乙烯磺酸钠浓度等于1.298 mmol/L=CCMC/10时,不产生新核心。同时为避免单体自聚结块, 采用多次投料的方法,成功制备单分散性良好的聚苯乙烯微球。更多还原

【Abstract】 The emulsion seed growth is used to develop 500 - 600 nm monodisperse polystyrene microspheres in this paper. Conditions in which new cores are produced in the method are studied. When the concentration of emulsifier(sodium styryl sulfonate)is equal to 1.298 mmol/L= CCMC/10, new cores aren’t produced. With an eye to the method of agents being put in many times in order to avoid the self -polymerization of the styrene, polystyrene microspheres with good monodisperse are successfully prepared.更多还原
