| 摘 要： | 以乙醇／水（EtOH／H2O）溶剂为反应介质，以过硫酸铵（AFS）和聚乙烯醇（PVA）或聚乙二醇（PEG）为引发剂和稳定剂，利用显微分析观察当改变稳定剂的种类时，丙烯酰胺（AM）分散聚合粒子形态的变化。研究发现：以PVA-0488，PEG-1000和FEG-2000为稳定剂时所得粒子为球状，而以PVA-1788或PVA-1799为稳定剂时所得粒子为短棒状。

| Abstract: | Polyacrylamide（PAM） was synthesized by dispersion polymerization with PVA or PEG and ammonium persulfate（APS） as stabilizers and initiator in alcohol/water medium. The effect of stabilizer types on particle shapes was discussed by microscopic analysis. The results show that the shape of prepared particles is ball-like while PVA-0488, PEG-1000 and PEG-2000 are used as stabilizers ;and the shape of prepared particles is short rod-like while PVA-1788 or PVA-1799 is used as stabilizer, respectively. |
