摘要
本文利用DSC,红外光谱,核磁共振等方法研究了四价钼体系聚合所得1,2-PB的结构与性能,讨论了1,2-PB的分予链结构对物理性能的影响,并将玻璃化温度与链结构参数间的关系式修订为:T_s=91v+220S^2—106,该式能够很好地描述钼系催化合成的高乙烯基聚丁二烯。
The structure and the properties of 1,2-polybutadienes prepared with molybdenum catalyst system were studied by DSC, IR and NMR methods, and the effects of configuration of 1,2-units on the properties of 1,2-polybutadiene also discussed. The relation between T8 and the molecular chain structure was revised as T8=91V+220S2-106 which describes the high vinyl polybutadienes well.
