摘　　要：合成了组成为ＬｎＣｌ３·３ＰＡ的丙酰胺氯化稀土配合物（Ｌｎ＝Ｐｒ，Ｎｄ，Ｅｕ，Ｄｙ；ＰＡ＝Ｃ２Ｈ５ＣＯＮＨ２）．ＩＲ表明，丙酰胺是通过酰胺基团的Ｏ与Ｎｄ进行配位．ＮｄＣｌ３·３ＰＡ配合物与烷基铝组成的二元体系，无论是三异丁基铝，二异丁基氢铝或者是三乙基铝都对丁二烯聚合具有较高的催化活性，而且所得聚丁二烯的顺式－１，４结构含量都在９８％以上．The lanthanide complexes LnCl 3·3PA(Ln=Pr,Nd,Eu,Dy; PA=propionamide) were synthesized. The IR results showed that PA is coordinated with Nd via its oxygen atom. The binary catalyst systems consisted of NdCl 3·3PA with i Bu 3Al, i Bu 2AlH, or Et 3Al were all found to be very active for butadiene polymerization when the cis 1,4 content of polybutadiene is 98% or more.
