Homopolymerization of butadiene has been carried out with a new series of binary catalyst system Nd(OR)3-nCln-AlEt3 and the catalytic activity as well as the microstructure of the resulting polymer have been studied. The results indicate that the stereospecificity of the polybutadiene obtained with these beinary catalyst system (when n=2) is similar to that prepared with thernary system Nd(OR)3-Al2Et3Cl3-AlEt3, yet the catalytic activity of the former is somewhat higher. Hence, it is possible that the present simpler binary system is more preferable to be applied than the ternary. System in butadiene polymerization.
