| 摘 要： | 利用13C NMR对抗冲聚丙烯的微结构进行了研究.结果表明,由于抗冲聚丙烯聚合工艺的差别,4个抗冲聚丙烯样品中的乙烯链段的序列分布也不同.根据抗冲聚丙烯的13C NMR谱,计算出了丙烯段的次甲基和甲基的峰强度,由此建立了表征抗冲聚丙烯共聚物中丙烯链段的立构规整度的方法.

| Abstract: | The microstructures of impact polypropylenes were investigated by 13C NMR spectroscopy.It was found that the ethylene sequence distributions were different in various impact polypropylenes made through distinctive manufacturing procedures. Isotacticity in the porpylene sequences of these copolymers were determined directly from 13C NMRspectra in methyl region with the aid of methine Peaks. |
