Poly (styrene-4-vinylpyridine)-neodymium complexes (NdCl3·PS4VPY) with various contents of the functional group and neodymium have been prepared and characterized. The infrared and X-ray photoelectron spectra indicate that the uncoordinated 4vinylpyridine (4VPY) units remain in the NdCl3·PS4VPY complexes. A novel binary catalytic system for butadiene polymerization can be formed from NdCl3·PS4VPY and iBu3Al, showing a catalytic activity much greater than the similar low molecular catalysts.
