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。

Abstract: The lanthanide complexes LnCl3·3PA(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 NdCl3·3PA with i-Bu3Al, i-Bu2AlH, or Et3Al were all found to be very active for butadiene polymerization when the cis-1,4-content of polybutadiene is 98% or more.

Key words: butadiene, coordination polymerization, propionamide, lanthanide complex
