Mesoporous silica-supported zirconocene catalysts for highly isotactic polypropylene.
نویسندگان
چکیده
A new bis(indenyl)zirconocene bearing a pendant Si-Cl anchor has been grafted onto MCM-41, SBA-15, MCM-48 and a disordered mesoporous silica for the polymerisation of ethylene and propylene, producing polymers with very high molecular weights, low polydispersities and, in the case of polypropylene, higher levels of isotacticity than obtainable with analogous homogeneous systems.

A theoretical reasoning on why coordination catalysts supported on mesoporous supports produce HDPE crystalline nanofibers but not iPP crystalline nanofibers
Since 1999, when Takuzo Aida proposed the preparation of high density polyethylene (HDPE) crystalline nanofibers through polymerization of ethylene by a Cp2 TiCl2 /MCM-41 catalyst, many researchers have published various papers on different aspects of the idea. The published researches show that the endeavors to polymerize other types of alpha olefins, especially propylene, to obtain polyolefin...
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 کاملFe3O4/FDU-12: A highly efficient and magnetically separable nano-catalyst for oxidation of alcohols
A series of Fe3O4 supported on mesoporous FDU-12 silica systems were prepared by the hydrothermal conditions. The surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like FTIR, XRD, N2 adsorption–desorption and TEM. XRD and adsorption–desorption analysis shows that the mesostructure of FDU silica remains intact after Fe3O4 modifications, wh...
