本文以GMA(Glycidyl methacrylate)和IDA(Iminodiacetic acid)合成出一具有螯合性官能基之單體 GMA-IDA，使之與苯乙烯(styrene)進行無乳化劑乳化聚合。再利用合成出之一系列乳液螯合銀離子，以UV還原方式得到奈米銀金屬微粒。探討單體配比、共溶劑對乳化聚合合成顆粒之粒徑、表面官能基之影響，及其對後來成長銀顆粒的影響。利用重量法、EA、IR測定合成乳液之組成，EA、官能基滴定瞭解顆粒型態，再使用TEM觀察成長之金屬顆粒。
　　由改變單體比可藉由離子型單體所提供的電荷穩定效果來改變粒徑、共溶劑的使用可以有效降低GMA-IDA homopolymer的產生，而不同共溶劑的使用量會因改變溶解度參數差異及電荷排斥力的關係使粒徑出現一最小值，實驗亦藉由影響聚合過程而得到不同表面官能基濃度的乳液，再利用計算得來的結果進而調控奈米銀金屬微粒的大小及分佈。由TEM觀察得知，可控制成長之奈米銀金屬微粒在5~30nm之間。

　　GMA-IDA with chelating function groups was synthesized by Glycidyl methacrylate(GMA) and Iminodiacetic acid(IDA). It can go soap-less emulsion polymerization with styrene and then got a serious of latexs. After the serious of latexs chelatingwith Ag+,we can get nano sliver metal particles by ultraviolet irradiation. The essay try to discuss the influence of different ratio of monomer and co-solvent on the diameter of latexs, particle surface function groups and the correlation of final Ag particle. The composition of latexs is tested by gravity method, EA and IR. The morphology of particle is analyzed by EA function group titration. Finally, we observe the growing metal particle by TEM.
　　Due to change the ratio of monomer, the ionic monomer can provide more electrostatic repulsion to change the diameter. The use of co-solvent can decrease GMA-IDA homopolymer. Moreover, the amount of different co-solvent will cause to min diameter for various solubility-parameter different and charge repulsive. The experiment got latexs with different concentration of surface function groups and dominate the size and distribution of nano Ag particle according to the calculated result. Finally, we can control the growth of nano Ag particle between 5~30nm by the observation of TEM.
