研究了某些电子给予体在丙烯聚合反应阶段的调变作用,得出了电子给予体的添加浓度(电子给予体/钛原子的摩尔比),电子给予性和分子体积大小对催化剂性能的影响。芳香酸酯具有较佳的调变作用,红外光谱研究了它与催化剂组份之间的相互作用。
The modulation effect of some electron donor on the polymerization stage of propylene was studied. The effects of the concentration of electron donor (molar ratio of electron donor / titanium atom), electron donating and molecular volume on the catalyst performance were investigated. . Aromatic acid esters have better modulation effect, infrared spectroscopy of its interaction with the catalyst components.
