摘　　要：Aroylhydrazones,formed by condensation of benzoylhydrazine with benzoylaldehyde,2-methoxybenzoylaldehyde and 2,4-dimethoxybenzoylaldehyde,reacted with TiCl 4 to form their corresponding complexes.The titanium complexes were characterized by elementary analysis,IR,and 1H-NMR.Their catalytic properties for ethylene polymerization performed up to 104gPE/(molTi·h).The resultant PE was studied by DSC,GPC,WAXD,FT-IR analyses.The results reveal that the product obtained is a typical linear polyethylene.Aroylhydrazones, formed by condensation of benzoylhydrazine with benzoylaldehyde 1 2-methoxybenzoylaldehyde and 2, 4-dimethoxybenzoylaldehyde, reacted with TiCl4 to form their corresponding complexes. The titanium complexes were characterized by elementary analysis, IR, and H-1-NMR. Their catalytic properties for ethylene polymerization performed up to 10(4) gPE/(molTi(.)h). The resultant PE was studied by DSC, GPC, WAXD, FT-IR analyses. The results reveal that the product obtained is a typical linear polyethylene.
