• 中文摘要： 甲基丙烯酸甲醋在乳化聚合中顯示特別之成核特性。在某些轉化率時會出現大量之新粒子成核。乳化聚合過程中平均粒徑及粒子數凶E烈震盪反映有積聚一解聚之程序存在。某些水相中成核之甲基丙烯酸酯分子可能存在粒子一水相界面，進而引發粒子可逆凝絮。
• 英文摘要： Methyl methacrylate (MMA) showed a characteristic nucleation behavior in emulsion polymeriza-tion. The nucleation of new particles occurred overwhelmingly at some conversions. The vigorousfluctuations in average particle size as well as particle number during emulsion polymerization showedthe existence of a deaggregation-aggregation process. It is proposed that some of the PMMA moleculesformed in the water phase may be present at the interface between the particles and the water phase, andmay induce reversible flocculation.
