| 摘 要： | <正> ~(13)C-NMR谱是目前认为用来研究高聚物序列分布的较好方法。对各种聚苯乙烯的序列分布,前人已做了许多工作,然而无论是对亚甲基(CH_2)或对芳C_1进行分峰,各谱峰的归属及其序列分布统计都没有一致的意见。

| Abstract: | The 13C-NMR spectra of radical and anionic polystyrene have been studied. Resolution of the aromatic C1 spectra has been made by computer. The resolced peaks have been assigned as pentad sequences and their probablities have been calculated. Experimental and cal-culated resultes show that the sequence distributions of radical and anionic polystyrene obey first order Markovian statistics. The polymers observed are all syndiotactic-rich. |
