Determination of kinetic parameters for ethylene polymerization (with and without hydrogen) by Ziegler-Natta catalyst. [PDF]

open access: greenPolyolefins Journal, 2020
In this study, slurry polymerization kinetics of ethylene with TiCl4/Mg(OEt)2/AlR3 Ziegler-Natta catalysts in various conditions using the model of sum square error (SSE) (method I) and model of least square error (LSE) (Method II) was investigated.

Síntese de catalisadores Ziegler-Natta: algumas rotas e suas dificuldades Synthesis of Ziegler-Natta catalysts: some routes and their difficulties [PDF]

open access: goldQuímica Nova, 1997
The Ziegler-Natta catalyst and the polymerization thereof are systems which require careful handling and special treatment of chemicals. In spite of the use of inert atmosphere and dry chemicals, some Ziegler-Natta systems may present low activities or ...

Imido-modified SiO2-supported Ti/Mg Ziegler-Natta catalysts for ethylene polymerization and ethylene/1-hexene copolymerization [PDF]

open access: yesPolyolefins Journal, 2016
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 ...
