中文摘要
本實驗使用批次反應器由無乳化劑之乳化聚合反應製備高分子乳膠溶液,以AIBA與KPS為起始劑,MMA與NVF被分解後之自由基的作用而共聚合成poly(MMA-co-NVF)的高分子顆粒,高分子顆粒分散在水相中形成高分子乳膠溶液。高分子乳膠溶液內的高分子顆粒之表面性質是決定乳膠溶液的穩定程度的主角,所以poly(MMA-co-NVF)顆粒在水相中的分散之穩定程度是由顆粒表面的親水性官能基與水分子產生界面作用力來決定。Poly(MMA-co-NVF)顆粒之合成以MMA/NVF之進料重量比、單體濃度與起始劑濃度為變因,藉此合成出多種Poly(MMA-co-NVF)顆粒,利用這些顆粒探討變因對顆粒的大小與組成的影響。由光散射粒徑分析儀與SEM觀察高分子顆粒大小與粒徑分佈情況。Poly(MMA-co-NVF)顆粒是由NMR鑑定整體MMA/NVF的組成莫耳比。Poly(MMA-co-NVF)顆粒表面組成的元素比與顆粒表層之元素比的縱度變化運用XPS量測。Poly(MMA-co-NVF)顆粒由整體MMA/NVF的組成莫耳比與顆粒表面的元素分析之比較確定顆粒表面具有的較多的NVF鏈段,再藉由表層之元素的縱度變化確定表面與內層的NVF鏈段變化,而建立Poly(MMA-co-NVF)顆粒的成核機制。
Abstract
Poly(methyl methaceylate-co-N-vinylformamide)was synthesized through soap-free emulsion copolymerization. The formation of monodisperse Poly(methyl methaceylate-co-N-vinylformamide)latex particles in absences of added surfactant has been studied by sampling polymerization reactions at different variables and determining the surface and bulk propersity of the latsx. Monodisperse and “clean” polymer lattices have found wide application in calibration of various measuring instruments and techniques. The surface propersity of polymer particles play an important role determining the colloid behavior of latex. Recently researchers have haves shown interest in the preparation and application of polymer particle because of the ease to control surface properties, like hydrophobicity, functional groups and morphology. The surface characteristics mainly depend on the type of initiator used, adsorbed or grafted surface-active agents and polymeric species.
Submicron-sized poly(methyl methaceylate-co-N-vinylformamide)particle was by soap-free emulsion copolymerization. The soap-free emulsion copolymerization were carried out with varying proportions of methyl methacrylate and N-vinylformamide.
