| 摘 要： | 采用偶氮二异丁脒盐酸盐(AIBA)作为光引发剂,光引发聚合并研究了阳离子表面活性单体——甲基丙烯酰氧乙基二甲基苄基氯化铵(DMBAC)的均聚及其与丙烯酰胺(AM)共聚合反应的动力学行为,聚合反应均在高于DMBAC临界胶束浓度(CMC)的条件下进行.研究结果显示DMBAC均聚合反应速率与引发剂浓度的0.29次方以及单体浓度的0.89次方成正比,均聚合反应的表观活化能约为13.74 kJ/mo1;DMBAC与AM共聚合反应速率与引发剂浓度的0.82次方以及单体总浓度的0.83次方成正比,共聚合反应的表观活化能约为10.97 kJ/mo1;同时测得DMBAC与AM共聚合反应的单体竞聚率为r1=0.27(AM)、r2=2.00(DMBAC),说明AM趋向于形成共聚物,而DMBAC更趋向于形成均聚物.

| Abstract: | Kinetic behaviors of the homopolymerization of(N,N-Dimethyl-N-methacryloyl oxyethyl-N-benzyl)ammonium chloride(DMBAC) and the copolymerization between DMBAC and AM were studied.Polymerizations were carried out above the critical micelle concentration(CMC) of DMBAC,and the initiation process was carried out photochemically using 2,2'-Azobis(2-methylpropionamidine) dihydrochloride(AIBA)as a photoinitiator.The results indicate that the rate of the homopolymerization is proportional to the concentration of phot... |
