英文摘要 | Copolymerization of ethylene/1-octene with three ansa-zirconocene/MAO catalyst systems were investigated. The polymerization activity is dependent upon the influence of electronic effects. It decreases in the following order: C6H4(CH2)(2)Cp2ZrCl2 > C5H3N(CH2)(2)Cp2ZrCl2 > CH3N(CH2)(2)ZrCl2. The composition and sequence distribution of copolymer were calculated from C-13-NMR spectra. It was found that the activityes of three ansacatalysts were lower than Et(Ind)(2)ZrCl2 under the same 1-octeone concentration. And their copolymer had lower 1-octene incorporation than that of Et(Ind)(2)ZrCl2. Other properties such as molecular wieght, melting point of copolymer were compared. |
