摘要: 含氮聚合物是一类很有意义的配位体,它在某些反应的催化过程中起载体作用。在含氮聚合物中,聚(苯乙烯-4-乙烯基吡啶)(PS4VPY)也是一种很重要的配体,因其杂环氮原子有一定的反应能力和配位能力。聚(4VPY)过渡金属(如Co、Ni、Cu和Zn)配合物已有报道。但PS4VPY的稀土配合物未见报道。本文报道NdCl3·PS4VPY的合成和表征,及催化活性。

Abstract: 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.

Key words: poly (styrene-4-vinylpyridine), neodymium complex, infrared spectrum, X-ray photoelectron spectrum
