| 中文摘要 | a new type of multifunctional ammonium modifier with carbonyl group and vinyl group was synthesized to prepare multifunctional montmorillonites (f-mmts), which were used as multifunctional catalyst supports for in situ ethylene polymerization. high loading of metallocene catalyst in the galleries of f-mmt had been achieved due to the presence of carbonyl group in the multifunctional modifier. xrd profiles and tem images showed that polyethylene/montmorillonite (pe/f-mmt) nanocomposites with exfoliated structure could be synthesized using the intercalated catalyst described above, even when the content of mmt was very high (more than 15.1 wt%). the as-produced pe/f-mmts nanocomposites were composed of flower-like particles with a diameter of about 5 pm. a thermal stable monoclinic phase was observed in pe/f-mmt nanocomposites. comparatively, the resultant pe/f-mmt nanocomposites showed low gas permeability. interfacial interaction between pe matrix and f-mmt was enhanced due to the chemical linking between the two components via copolymerization of ethylene with vinyl group of f-mmt. thus the resultant pe/f-mmt nanocomposites showed good structural stability.
