Synthesis of Propionamide Complexes with Lanthanide Chloride and Catalytic Activity of Its NdCl3 Complex in Butadiene Polymerization
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.
