An unusually stable supported bis(cyclopentadienyl)titanium dichloride-trialkylaluminum catalyst system for ethylene polymerization

A magnesium chloride supported bis(cyclopentadienyl)-zirconium(IV) dichloride catalyst for the polymerization of ethylene

“…In an earlier report from this laboratory we demonstrated that supporting Cp 2 TiCl 2 on MgCl 2 results in an interesting modification of the catalyst behavior towards the polymerization of ethylene 13,14) . This paper extends this study to the synthesis of a magnesium chloride supported Cp 2 ZrCl 2 catalyst and explores the behavior of such a catalyst system for the polymerization of ethylene.…”

FI Catalyst for Polymerization of Olefin

“…Up to now, several highly active transition metal complexes including metallocenes with MgCl2-based activator catalyst systems, often introduced as MgCl2-supported catalyst systems, have been reported [90,91]. These catalyst systems normally give polymers with broad molecular weight distributions.…”

Study on ethylene (co)polymerization and its kinetics catalyzed by a reversible crosslinked polystyrene‐supported metallocene catalyst

“…Recently a large amount of research dealing with heterogenization of metallocene using inorganic materials [1][2][3] or organic materials 4 -6 as carriers has been published. However, despite the evident advantage of heterogeneous metallocenes systems compared to homogeneous metallocenes systems, heterogeneous metallocene catalyst systems still remain an unsolved problem.…”

“…Furthermore, organic materials can be easily functionalized to satisfy certain requirements. Yang et al 7 studied the polymer-bound Cp anion, which reacted with Ti(O-Bu) 3 Cl to form polystyrene-bound Ti(O-Bu) 3 . However, the catalyst was not characterized in detail.…”
