摘要
本文研究了甲基丙烯酸甲酯同N-芳基取代甲基丙烯酰胺的共聚合反应。并制得了这些共聚物包括甲基丙烯酸甲酯(MMA)-co-N-对甲苯基甲基丙烯酰胺(N-p-TMA);甲基丙烯酸甲酯-co-N-苯基甲基丙烯酰胺(N-PhMA);甲基丙烯酸甲酯-coc-N-对溴苯基甲基丙烯酰胺(N-p-BrPhMA)和甲基丙烯酸甲酯-co-N-对硝基苯基甲基丙烯酰胺(N-p-NPhMA)。 用~1H-NMR方法测定了这些共聚物中两种单体的组成。再参照Fineman-Ross公式估算出了这些共聚体系中各组单体的竞聚率。讨论了各种酰胺的活性。
The copolymerization of methylmethaerylate (MMA) with N-2rylmethacrylamide (N-ArMA) was studied. The methylmethacrylate-co-N-p-tolylmethacrylamide (MMA-co-N-p-TMA), methylmethacrylate-co-N-phenylmethacrylamide (MMA-co-N-PhMA), methylmet-hacrylate-co-N-p-Bromophenylmethacrylamide (MMA-co-N-p-BrPhMA) and methylmethac-rylate-co-N-p-nitrophenylmethacrylamide (MMA-co-N-p-NPhMA) copolymers were prepared. The composition of the copolymers was determined by 1H-NMR method. The monomer reactivity ratios were calculated by Fineman-Ross method from the copolymer composition data.The activity of the copolymerization of various N-ArMA with MMA was discussed.
