| 摘要: 本文合成了两个新的催化剂，苯基-三苯基膦-[N-萘基-3-甲基水杨醛亚胺]合镍(4a)与苯基-三苯基膦-[N-萘基-5-硝基水杨醛亚胺]合镍(4b)，并研究了它们催化降冰片烯的聚合。发现两种催化剂在助催化剂甲基铝氧烷(MAO)存在下都具有良好的催化降冰片烯聚合物活性。在50 ℃时，催化剂4b表现出最高催化活性。 |

| Abstract: Two new catalysts, phenyl-triphenylphosphorous-[N-naphthyl-3-methylsalicylaldiminato] nickel (4a) and phenyl-triphenylphosphorous-[N-naphthyl-5-nitrosalicylaldiminato] nickel (4b) have been synthesized. Complexes 4a and 4b can be used as catalysts for norbornene polymerization in the presence of MAO as co-catalyst. Both of 4a and 4b showed high activity. At 50 ℃, catalyst 4b showed the highest activity. |
