本文报导甲基丙烯酸异冰片酯(IBMA)与N-对溴苯基甲基丙烯酰胺(N-p-BrPhMA)的共聚物(用IBMA-co-N-p-BrPhMA表示)的制备。并给出了共聚物的红外光谱和核磁共振氢谱。 用~1H-NMR方法测定了共聚物的组成。参考Fineman-Ross方程计算了共聚体系中单体的竞聚率分别是r_1=0.72±0.02(N-p-BrPhMA);r_2=0.30±0.02(IBMA)。 比较了IBMA与MMA、MA对N-p-BrPhMA的反应活性,其顺序是: MMA(1/r=2.50)>MA(1/r=1.59)>IBMA(1/r=1.39) 共聚体是硬的无色透明的玻璃体。
This paper reports the preparation of a copolymer of isobornyl methacrylate (IBMA) and N-p-bromophenylmethacrylamide (N-p-BrPhMA) represented by IBMA-co-N-p-BrPhMA. The infrared spectrum and 1H-NMR spectrum of the copolymer were also given. The composition of the copolymer was measured by ~ 1H-NMR method. The reactivity ratios of the monomers in the copolymerization system were calculated according to the Fineman-Ross equation as follows: r 1 = 0.72 ± 0.02 (N-p-BrPhMA); r 2 = 0.30 ± 0.02 (IBMA). The reactivity of IBMA with MMA, MA to Np-BrPhMA was compared in the order: MMA (1 / r = 2.50)> MA (1 / r = 1.59)> IBMA Colorless transparent glass body.
