Abstract: The effect of methylaluminoxane(MAO) on butadiene polymerization catalyzed bypolynuclear Nd-Al bimetallic complex has been examined.Compared with alkylaluminiumMAO could improve the activity of the catalyst system to a higher extent even at n(Al)/n(Nd) 5~20 mol/mol.The chain transfer seems to be lower by using MAO than that by using alkylaluminium.

Key words: butadiene, stereospecific polymerization, Nd-Al bimetallic complex, methylaluminoxane
