| 英文摘要 | MgCl2 supported Ziegler-Natta catalyst containing a novel asymmetric diether as internal donor was prepared for polymerization of propene. The effects of polymerization temperature and the n (Al)/n(Ti) ratio on the catalytic activity and the molecular weight, the isotacticity and the melting point of polypropene were investigated. In comparison with the symmetric diether catalysts, the catalytic activity and the isotacticity of polypropene were much lower. The stereosequence distributions were analyzed by means of C-13 NMR and the results obtained indicate that isotactic, syndiotactic and iso-syndiotactic block polypropenes were produced. The stereo effect of MBF and the polymerization mechanism were discussed. |
