| 摘 要： | 本研究以2,6-二乙酰基吡啶、2,4,6-三甲基苯胺和FeCl2.4H2O为原料,制备了后过渡金属铁的二亚胺配合物。将其负载在改性蒙脱土上,以己烷为溶剂、AlEt3为助催化剂进行聚合反应。通过红外光谱、X射线分析、热分析等,系统地研究了蒙脱土的改性条件对蒙脱土结构、蒙脱土载体铁系催化剂的聚合行为及聚合物结构与热性能的影响。研究表明最佳插层条件是：1831为插层剂、80℃、反应2 h、蒙脱土/1831（质量比）为3/1,此时层间距为2.72 nm,催化剂活性达1.073×106（g PE/mol Fe.h）,聚乙烯堆密度为0.351g/cm3,形成MMT/PE纳米塑料。 |

| Abstract: | In this study,used 2,6-diacetyl pyridine,2,4,6-trimethyl aniline and FeCl2 · 4H2O as raw materials,prepared diimine complexes of late transition metal Fe.Loaded on the modified montmorillonites,it had a polymerization with hexane as solvent,AlEt3 as promoter.By infrared spectroscopy,X-ray analysis,thermal analysis,a systematic study was carried on effects of montmorillonite structure,polymerization behavior of montmorillonite carrier iron-based catalyst,polymer structure and thermal properties to modification conditions of montmorillonites.The study indicated that the optimum intercalation conditions were： 1831 as the intercalation agent,80℃,reaction of 2 h,MMT / 1831（mass ratio） was 3 / 1,layer spacing of 2.72 nm,the catalytic activity of 1.073 × 106（g PE / mol Fe · h）,polyethylene bulk density was 0.351g/cm3,MMT / PE nano-plastics was formed. |
