• 中文摘要： 本文旨在探討兩性離子單體3-二甲基(丙烯酸乙基)銨丙烷磺酸鹽〔3-dimethyl( acryloyloxyethyl)ammonium propane sulfonate, DAAPS〕與丙烯醯胺(acrylamide)或N-乙烯基-氮伍圜酮(N-vinyl pyrrolidone)在水溶液中的共聚合反應。實驗發現N-乙烯基-氮伍圜酮與DAAPS的共聚合速率明顯地比丙烯醯胺與DAAPS的共聚合速率慢。單體的反應性是以Fineman-Ross和 Kelen-Tudos法來計算。使用Fineman-Ross處理時, DAAPS-AM共聚合之 r/sub 1/.bcdot.r/sub 2/=0.06, DAAPS-VP之r/sub 1/.bcdot.r/sub 2/=0.04都顯示出此共聚合反應趨向於交替共聚合, 又使用 Kelen-Tudos處理時, 相同的現象也可以觀察到。共聚合體之微細構造則是以廣範圍的進料組成經過反應性比的數據, 預期其交替共聚合之莫耳百分率。
• 英文摘要： Copolymerization of ampholytic monomer, 3-dimethyl(acryloyloxyethyl)ammonium propane sulfonate, DAAPS, with acrylamide or N-vinyl pyrrolidone was studied in aqueous solution. Rate of copolymerization of N-vinyl pyrrolidone with DAAPS was found to be remarkably slower than that of acrylamide. The monomer reactivity ratios were calculated by the Fineman-Ross and Kelen-Tudos methods. The DAAPS-AM copolymers with r/sub 1/.bcdot.r/sub 2/=0.06 and DAAPS-VP copolymers with r/sub 1/.bcdot.r/sub 2/=0.04 using Fineman-Ross treatments exhibit a tendency toward alternation. Similar phenomenon was observed by using Kelen-Tudos treatments. The microstructure was predicted for a wide range of feed composition through a knowledge of reactivity ratios.
