| 摘 要： | 本文利用红外光谱、~(13)C-NMR和线膨胀等方法研究了钼体系聚1,2-丁二烯的链结构,并研究了链结构的调节方法。发现烯丙基卤等极性添加剂既可以调节1,2-链节含量,又可以调节链节的立体构型。最后,利用统计理论估计了1,2-链节的各种异构体的平均序列长度。

| Abstract: | The chain structure of 1, 2-polybutadiene prepared with molybdenum catalyst system has been studied by IR, 13C-NMR, X-ray and thermal analysis, and the method to regulate the chain structure has been investigated. It was found that some of the polar additives, e.g., allyl halides are able to regulate not only the content of 1, 2-unit in the polymer, but also its configuration and sequence distribution. Attempt has been made to estimate the sequence length of stero-isomers of 1, 2-unit by statistical theory. |
