摘　　要：用纳米Fe3O4磁性粉末作为载体,负载α-二亚胺N i催化剂制得磁性纳米催化剂。通过乙烯在纳米催化剂粒子表面原位聚合得到既不同于结构型磁性材料也不同于普通复合型磁性材料的一种新型磁性支化聚乙烯材料。Polyethylene-Fe3O4magnetic nanocomposites were synthesized by in situ polymerization with bis （4-（4-amine-3,5-diisopropylbenzyl）-2,6-diisopropylphenylimino）acenaphtheneNiBr2 covalently supported on nanometer magnetic powder Fe3O4pretreated with triethyl aluminum （TEA）. The new kind of highly branched magnetic polyethylene that is different from both the composite plastics＇ magnet and the structure plastics＇ magnet was obtained. The catalysts and the obtained nanocomposites were examined with TEM.
