摘要：
Previously investigated Mg-Al-Ti catalyst has been modified by the application of AlEt3 cocatalyst instead of AlEt2Cl and by the prepolymerization process. Both ways of modifications have increased considerably the activity of the catalyst system studied in ethylene polymerization process. The investigations of active titanium catalyst obtained activated with AlEt3 have revealed the reason for non-linearity of the function of the ethylene polymerization reaction rate versus the catalyst concentration. Additionally, the application of the prepolymerization process has improved the morphology of PE obtained.
