The catalyst MgCl2/TiCl4/BMMF-AlEt3 prepared with a novel complex 9
9-his(methoxymethyl) fluorene(BMMF)as internal donor was applied to propene polymerization without any external donors and the isotacticity of polypropene obtained was over 95%.In comparison with the catalyst MgCl2/TiCl4/Phthalate-AlEt3/DDS
the catalyst of MgCl2/TiCl4/BMMF·AIEt3 showed high activity.The effects of polymerization conditions such as temperature and Al:Ti ratio on the activity of catalyst
on the molecular weight
the isotaticity and the melting point of polypropene were studied.Polypmpene Was characterized by 13C-NMR spectroscopy and the structure of polypropene Was studied.
