The bimetal complexes supported on styrene-acrylic acid copolymer (SAAC.Nd.Na. and SAAC.Nd.Fe) have been presence of a new type catalyst system composed of these complexes has been studied. We have found that the system activity is optimum when Nd and free function group -COOH molar ratio in the bimetal complexes is lower. For SAAC.Nd.Fe the system activity decreases gradually with increasing the Fe content. For SAAC.Nd.Na metal Na can promote the system activity
no matter whether the content of Na in the bimetal com-plexes is much or little. Only when the molar ratio of Nd to -COOH is lower
the activity increase is greater. In addition
the activity of the putadiene polymerization catalyzed by SAAC.Nd.Fe-AlEt Cl-Al(i-Bu) in the presence of phenanthroline and the relationship bet-ween the polybutadiene microstructure obtained with the content of Fe in SAAC.Nd.Fe were studied.
