摘 要:本文通过一步法制备了新型的苯胺基肟类中性钯催化剂,并通过核磁氢谱、核磁碳谱、元素分析对相应的配体和催化剂结构进行了测试表征,结果表明,成功制备了所设计的配体以及相应催化剂。进一步研究了钯催化剂对催化降冰片烯单体的均聚合行为,结果表明,钯催化剂在助催化剂dMMAO作用下,可高活性催化降冰片烯单体的均聚合,活性高达540kg/(molPd·h);同时发现,该催化剂的热稳定性好,可以在80℃以较高活性催化降冰片烯单体均聚合。New aniline oxime neutral palladium catalyst was prepared by one-step method and characterized by 1H NMR,13C NMR and elemental analysis.The results showed that the designed ligands and the corresponding catalysts had been successfully prepared.Homopolymerization of norbornene with palladium catalyst was studied.The results showed that palladium catalyst could catalyze the homopolymerization of norbornene with high activity,up to 540 kg polymer/(mol Pd·h) with dMMAO as cocatalyst.Moreover,the catalyst had good thermal stability,homopolymerization of norbornene monomers could be carried out at 80 ℃ with high activity.
