合成了烯丙基对甲基水杨醛亚胺和环戊烯基对甲基水杨醛亚胺配体,并与trans-[NiCl(Ph)(PPh3)2]反应合成了配合物[O-(3-allyl)(5-CH3)C6H2-o-C(H)∶N-2,6-C6H3(i-Pr)2]Ni(PPh3)(Ph)和[O-(3-cyclopentenyl)(5-CH3)C6H2-o-C(H)∶N-2,6-C6H3(i-Pr)2]Ni(PPh3)(Ph),以MS,1H NMR和元素分析对配体及配合物进行了表征.在Ni(COD)2(COD环辛二烯)助催化下成功地催化乙烯聚合,在808 kPa的压力下,前者配合物的最高活性可达265 kg/(mol·h),聚乙烯的粘均分子量在(0.95~3.85)×104间; 后者配合物的最高活性可达434 kg/(mol·h),聚乙烯的粘均分子量在(0.87~5.81)×104间.添加THF,CH3COOEt和EtOEt对催化聚合性能无显著影响,添加甲基丙烯酸甲醇则不仅不发生共聚,相反严重降低了催化活性.
