摘　　要：合成含2-氨基苯基二苯基膦水杨醛配体(三啮P^N^O配体)的3个后过渡金属镍配合物催化剂;采用元素分析、红外光谱和单晶衍射实验等方法对配合物的结构进行表征;研究了配合物对降冰片烯聚合的催化活性和影响因素.实验表明,在以甲基铝氧烷(MAO)为助催化剂时,配合物对降冰片烯聚合显示出良好的催化活性;聚合产物呈现良好的热稳定性和较为粗糙的表面形态.A P^N^O ligand（2-aminophenyldiphenylphosphine salicylaldiminato ligand） and corresponding late transition metal nickel（Ⅱ） complexes were synthesized and characterized by elemental analysis,FT-IR and X-ray single crystal diffraction.The nickel complexes were used to catalyze norbornene polymerization activated with methylaluminoxane（MAO）,and the specific catalytic activities were evaluated at different polymerization conditions.It was found that the complexes exhibit high activities for the vinyl addition polymerization of norbornene,and the polymer shows high thermal stability and none-crystalline structure.
