| 摘 要： | 等规指数是表征聚合物分子排列规整程度的技术指标,国标萃取法操作复杂,分析时间长,已经不能满足聚丙烯合成工业发展的要求.本文应用核磁共振法测定聚丙烯等规指数,以国标方法测得的数据作为标准建立工作曲线.该方法操作简单,样品用量少,分析速度快,不损伤样品,测试精度高.

| Abstract: | lsotactic index to characterize the degree of polymer molecules arranged in neat technical indicators, GB extraction complex operation, the analysis for a long time , has been unable to meet the requirements of polypropylene synthetic industrial development. In this paper, NMR determination isotactic index of polypropylene , with GB method measured data as a standard curve established. The method is simple , small amount of sample analysis speed, does not damage the sample , high precision . |
