摘要
On the basis of new methods of synthesis of magnesium-containing carriers with the use of soluble organomagnesium compounds a wide spectrum of supported titanium-magnesium and vanadium-magnesium catalysts of various composition with controllable optimal morphology for obtaining versatile brands of polyethylene by suspension and gas-phase methods was elaborated. The usage of various modifications of these catalysts allows production of high amount (up to 1000 kg/g Ti) of polyethylene of high, medium, and low density with narrow and wide molecular weight distribution (including bimodal) as well as different brands of polyethylene ultrahigh molecular weight.
