二元离子型共聚物论文文献综述

刘海燕,苏连江,李卫宏,赵秀丽,陈成[1](2010)在《离子液体中AM/ST二元共聚物的合成》一文中研究指出采用1-丁基-3-甲基咪唑氟硼酸盐离子液体作为聚合反应介质,以偶氮二异丁腈(AIBN)为引发剂,丙烯酰胺(AM)为亲水单体,苯乙烯(ST)为疏水单体,合成了水溶性共聚物P(AM/ST).研究得到了适宜的反应条件:总单体在离子液体中的浓度为2mol/L,引发剂的浓度占总质量分数的2%,反应温度60℃,反应时间4h,AM与ST的物质的量比为98∶2,采用该反应条件所得到的聚合物的特性黏数为2.6.通过1HNMR,13CNMR和FIRT表征了聚合物的分子结构.(本文来源于《分子科学学报》期刊2010年03期)

朱麟勇,常志英,李妙贞,王尔鉴[2](2001)在《二元阴离子型丙烯酰胺共聚物在二价金属离子存在下相分离行为的研究》一文中研究指出Phase separation behavior of the water soluble binary anionic acrylamide copolymer series (P3A) composed of non ionic monomer acrylamide (AM), weak acidic monomer acrylic acid (AA) and strong acidic monomer 2 acrylamido 2 methylpropanesulfonate (AMPS) was studied in the Ca 2+ ion aqueous solution. The P3A was found to exhibit an unusual phase separation behavior, which relates with structure and composition of the polymer, as well as the concentration and temperature in the dilute P3A solution. A non linear relationship appeared between the critical temperature T c of phase separation and the metal salt concentration with a minimum at the mid position, whereas the T c remains constant as varying polymer concentration. From comparison of the effects of AA and AMPS units on the phase separation behavior of P3A polymers the results obtained indicate that except for the difference in acidity of two anionic units, the phase separation is mostly affected by the structure of anion unites in the polymer chain. The AMPS units exhibit a good stability under the action of Ca 2+ ions due to their great steric influence of side chains compared to AA units. Therefore, containing more AMPS, the polymer (P3A) becomes the more resistant to phase separation in the divalent metal salt solution.(本文来源于《高分子学报》期刊2001年03期)

傅绍斌,李外郎,顾惕人[3](1990)在《聚醚型非离子表面活性剂的混合表面膜 Ⅲ.环氧乙烷-环氧丙烷嵌段共聚物、聚丙二醇与十六醇、硬脂酸的二元混合物》一文中研究指出本文进一步研究了环氧乙烷-环氧丙烷嵌段共聚物(L61和F68)、聚丙二醇(PPG)分别与十六醇(CA)、硬脂酸(SA)所形成的二元混合膜.根据对π-a实验结果的分析,表明PPG-CA、PPG-SA、F68-SA和L61-SA的混合单分子膜是不相混溶的,而L61-CA和F68-CA的混合单分子膜则是混溶的.(本文来源于《化学学报》期刊1990年05期)

Phase separation behavior of the water soluble binary anionic acrylamide copolymer series (P3A) composed of non ionic monomer acrylamide (AM), weak acidic monomer acrylic acid (AA) and strong acidic monomer 2 acrylamido 2 methylpropanesulfonate (AMPS) was studied in the Ca 2+ ion aqueous solution. The P3A was found to exhibit an unusual phase separation behavior, which relates with structure and composition of the polymer, as well as the concentration and temperature in the dilute P3A solution. A non linear relationship appeared between the critical temperature T c of phase separation and the metal salt concentration with a minimum at the mid position, whereas the T c remains constant as varying polymer concentration. From comparison of the effects of AA and AMPS units on the phase separation behavior of P3A polymers the results obtained indicate that except for the difference in acidity of two anionic units, the phase separation is mostly affected by the structure of anion unites in the polymer chain. The AMPS units exhibit a good stability under the action of Ca 2+ ions due to their great steric influence of side chains compared to AA units. Therefore, containing more AMPS, the polymer (P3A) becomes the more resistant to phase separation in the divalent metal salt solution.
