| 中文摘要 | polymerization of propylene was carried out by using mgcl(2)-supported ticl(4) catalyst in conjunction with triethylaluminium (tea) as cocatalyst. the effect of polymerization temperature on polymerization of propylene was investigated. the catalyst activity was influenced by the polymerization temperature significantly and the maximum activity of the catalyst was obtained at 40 a degrees c. with increasing the polymerization temperature, the molecular weight of polypropylene (pp) drastically decreased, while the polydispersity index (pdi) increased. the effect of the two-stepwise polymerization procedure on the molecular weight and molecular weight distribution of pp was studied and the broad pdi of pp was obtained. it was also found that the pdi of pp could be controlled for propylene polymerization through regulation of polymerization temperature. among the whole experimental cases, the m (w) of pp was controlled from 14.5 x 10(4) to 75.2 x 10(4) g/mol and the pdi could be controlled from 4.7 to 10.2. |
