摘要: 本文研究定向稀土催化剂组份中引入镁铝络合物后对丁二烯聚合的影响。改变镁铝络合物与氯化物的种类和用量,皆明显的影响其聚合活性。当催化剂中含有苯基镁的烷基铝络合物时,聚丁二烯反-1,4链节可达36%。选择适当的催化剂组成和配比时,含镁稀土定向催化剂具有较高的聚合活性。

Abstract: The polymerization of butadiene using neodymium catalysts in combination with organomagnesium-organoaluminum complexes has been investigated. About 40% trans-1,4-polybutadiene was obtained when Ph2Mg was used as one of the catalyst. components Selecting an appropriate formula as well as an order of mixing of components are very important factors for obtaining good yield of high cis-1, 4-polybutadiene.
