| 摘 要： | The active center concentration C_p, the rate constant k_p, and the activation energy of chain propagation E_p in the polymerization of propylene with complex-type TiCl_3-(C_2H_5)_2AlCl catalyst system were studied. The Mn was corrected by (?) value determined by GPC. The values thus obtained for C_p, k_p, and E_p at 50℃were 3.01 mol/mol Ti, 6.27 1/mol·sec, and 5.10 Kcal/mol respectively.The kinetic parameters were compared with those obtained from conventional TiCl_3·AlCl_2 catalyst, showing that the higher activity of the complex-type catalyst over the conventional catalyst is not only due to the higher C_p of the former, but to a greater extent due to the increase of the k_p value.

| Abstract: | The active center concentration Cp, the rate constant kp, and the activation energy of chain propagation Ep in the polymerization of propylene with complex-type TiCl3-(C2H5)2AlCl catalyst system were studied. The Mn was corrected by Mw/Mn value determined by GPC. The values thus obtained for Cp, kp, and Ep at 50℃ were 3.01 mol/mol Ti, 6.27 1/mol·sec, and 5.10 Kcal/mol respectively. The kinetic parameters were compared with those obtained from conventional TiCl3·AlCl2 catalyst, showing that the higher activity of the complex-type catalyst over the conventional catalyst is not only due to the higher Cp of the former,but to a greater extent due to the increase of the kp value. |
