人们对位于周期表ⅢB族第21号元素鈨的催化性能研究极少。不久前,作者之一首次发现环烷鈨和烷基铝组成的络合催化体系可以使苯乙炔、已炔、戊炔等乙炔衍生物聚合,制得顺式结构含量和分子量都较高的聚炔烃。目前我们正在进行应用鈨化合物与烷基铝组成的络合催化剂于乙炔定向聚合的研究。研究表明环烷酸鈨或膦酸酯鈨与三异丙基铝或三乙基铝以及第三组份如α—乙基己基膦酸
There have been very few studies on the catalytic properties of the element No. 21 in Group IIIB of the Periodic Table. Not long ago, one of the authors found for the first time that a complex catalyst system consisting of cycloalkane and aluminum alkyl can polymerize acetylene derivatives such as phenylacetylene, acetylene and pentyne to obtain poly Alkynes. At present, we are conducting the research on the directional polymerization of acetylene using the complex catalyst composed of compound and aluminum alkyl. It has been shown that azelaic acid or phosphonite is reacted with triisopropylaluminum or triethylaluminum and a third component such as a-ethylhexylphosphonic acid
