Abstract

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
