Advantages of Group 4 Metallocene Bis(trimethylsilyl)acetylene Complexes as Metallocene Sources Towards Other Synthetically used Systems [PDF]
Active species for synthetic and catalytic applications are formed from well defined complexes or mixtures of compounds. For group 4 metallocenes, three pathways for the formation of the reactive complex fragment [Cp′2M] are known: (i) reductive mixtures

Metallocene Based Polyolefin Nanocomposites [PDF]
One of the most efficient and versatile ways to synthesize polyolefin nanocomposites is the in-situ polymerization of olefins in the presence of nano particles by metallocene catalysts. Metallocene/methylaluminoxane (MAO) catalysts are soluble in hydrocarbons and therefore they can be absorbed perfectly in solution onto the surface of particles or ...

The synthesis of metallocene calix[4]arenes
The condensation of 1,1′-bis(chlorocarbonyl)metallocenes andp-tert-butylcalix[4]arene in toluene leads to novel metallocene calix[4]arenes in which the metallocene subunit bridges the opposite hydroxy groups of the parent calixarene.

Copolymerization of ethylene with norbornene by using metallocene/TIBA/B(C6F5)3 system [PDF]
Cyclic olefin copolymer is a type of high-performance polyolefin material, which is prepared by using a single-site catalyst in solution polymerization. The common activator of this system is alkyl aluminoxane or organic boron/aluminum system.

Active site nature of magnesium dichloride-supported titanocene catalysts in olefin polymerization [PDF]
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 ...

Synthesis of Metallocene Catalyst for Terpolymerization of Ethylene, Propylene and Diene [PDF]
The bis(indenyl) zirconium dichloride catalyst was synthesized by a modified method at room temperature. Terpolymerization of ethylene, propylene and diene monomers were carried out using this metallocene catalyst under different conditions of different ...
