单分散聚甲基丙烯酸甲酯微球的制备

Preparation of Monodisperse Poly(Methyl Methacrylate)Microspheres

选择分散聚合方法制备微米级单分散聚甲基丙烯酸甲酯微球,改变反应物间的配比及反应条件,考察了引发剂浓度、稳定剂浓度对微球粒径的影响及变化规律,同时对微米级单分散聚甲基丙烯酸甲酯微球提出最佳的制备方案。

Monodisperse poly(methyl methacrylate)microspheres was prepared by the dispersion polymerization method.Through changing the ratio of reactants and reaction conditions,effects of polymerization conditions(such as initiator concentration,stabilizer concentration)on microsphere particle size were investigated as well as changing law of microsphere particle size.At last,the best preparation scheme of micron monodisperse PMMA microspheres was gained.
