Abstract

Abstract: The polymerization of butadiene catalyzed by the new binary iron catalysts FeCl_n·3L-AlR₃ (n = 2 or 3, L = P₃₅₀ or O = P(OBu)₃) has been studied.Polybutadiene having about 75% of cis-1,4 and 25% of 1,2 units was obtained.The obtimum Al/Fe ratio in the catalystsystem was found.The effects of monomer concentration, varity of iron complex andpolymerization temperature on polymerization of butadiene were examined.

Key words: butadiene, iron catalyst, binary catalyst, coordination Polymerization
