| 摘 要： | 本文研究了FeCl_3-(i-C_4H_9)_3Al-含氮配位体系对丁二烯聚合的催化活性。含一个氮的化合物对该体系聚合丁二烯的催化活性没有显著的提高。能与Fe形成五员螯合环的含氮化合物对活性提高有以下次序:邻啡啰啉>2,2′-联吡啶>>乙二胺或四甲基乙二胺。详细研究了FeCl_3-(i-C_4H_9)_3Al-邻啡啰啉体系聚合丁二烯的规律,该体系可以得到中乙烯基聚丁二烯。提出了丁二烯聚合的反应机理。

| Abstract: | It was found that the addition of compounds containing one nitrogen atom, such as pyridine, does not raise the catalitic activity in the polymerization of butadiene for the system of FeCls-(i-C4H9)3Al, and that the compounds containing two nitrogen atoms can incease the activity in the following order: 1, 10-phenanthroline>2, 2'-dipyridyl >> ethylenediamine or tetramethyl ethylenediamine. The polymerization of butadiene in the presence of FeCl3-(i-C4H9)3Al-phenanthroline have been studied in more detail. A possible mechanism is proposed. |
