- It was found that PVOZO, which still maintains oxazoline ring as a pendant group in the polymer, is of a linear macromolecule. 用元素分析和红外光谱表征的方法,证实了所得单体和聚合物的分子结构;
- A quantity of -CF_3 pendant group connected with the backbone of the terpolymer would strengthen its fused flowability without decreasing its molecu? ar weight. Therefore. 三元共聚物的主链上带有一定数量的-CF_3侧基,改善了共聚物的熔融流动性能,但并不降低分子量。
- In addition, the polystyrene backbone with epoxy pendant groups was also prepared by the similar method. 利用类似方法还合成了含环氧侧基的聚苯乙烯主链。
- The results showed that backbone polymers with DPE and epoxy pendant groups, having controlled molecular weight and narrow distribution, were obtained successfully. 用IR、~1H NMR、GPC和SLS(光散射)等测试方法对其进行了详细表征,并讨论了PSLi与DPE基团的比例和主链与侧链的分子量等因素对接枝率的影响,结果表明PSLi与DPE官能团的偶联反应是定量的,可以通过调节PSLi与DPE官能团的加料比来控制接枝率。
