Abstract: The composition of Nd-Al bimetallic complexes isolated from the reaction system of NdCl3·3P350 with AlR3 has been studied.The complexes can initiate the polymerization ofbutadiene and isoprene with a definite activity and high stereoregularity.The complex of HAl (i-Bu)2 system gives the highest polymerization activity.

Key words: rare earth catalyst, butadiene, isoprene, stereospecific polymerization
