Copolymerization of ethylene with α-olefins over highly active supported Ziegler-Natta catalyst with vanadium active component
The new highly active supported vanadium-magnesium catalyst (VMC) has been studied in α-olefin (1-butene, 1-hexene)/ ethylene copolymerization in the presence of hydrogen. Data on the effect of α-olefin/ethylene ratio in copolymerization on the content of branchings in copolymers, kinetic profile, copolymer yield, molecular weight and molecular weight distribution of copolymers have been obtain...
متن کاملImido-modified SiO2-supported Ti/Mg Ziegler-Natta catalysts for ethylene polymerization and ethylene/1-hexene copolymerization
A novel imido-modified SiO2-supported Ti/Mg Ziegler-Natta catalyst for ethylene and ethylene/1-hexene polymerization is investigated. The catalyst is prepared by modification of (SiO2/MgO/MgCl2)TiClx Ziegler-Natta catalysts via supporting vanadium species followed by reaction with p-tolyl isocyanate as imido agents, to get the merits from both the SiO2-supported imido vanadium catalyst and the ...
متن کاملActive site nature of magnesium dichloride-supported titanocene catalysts in olefin polymerization
Heterogeneous Ziegler-Natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. In our previous study, it was reported that MgCl2-supported titanocenecatalysts can generate both Ziegler-Natta-type and metallocene-type active sites according to the type of activators.The dual active site nature of the supported titanocene catalysts was furt...
متن کاملcopolymerization of ethylene and propylene using 4th generation ziegler- natta catalyst: influence of cocatalyst, external electron donor and hydrogen
copolymerization of ethylene and propylene was investigated using a 4th generation phthalate ziegler-natta catalyst in normal hexane in a buchi reactor. the effects of different mole fractions of [al]/[ti], [si]/[al] and various amounts of hydrogen on productivity and weight percent of ethylene on the product, were studied. in the copolymerization reactions, tri-isobutyl aluminum (tibal) was us...
