Diastereomeric amido functionalized ansa half-sandwich complexes of titanium and zirconium as catalyst precursors for ethylene polymerization to give resins with bimodal molecular weight distributions
摘要:
A total of 20 diastereomeric amido functionalized ansa half-sandwich dichloride complexes of titanium and zirconium have been prepared and characterized. All complexes were used as catalyst precursors for ethylene polymerization. Since such catalysts consist of diastereomers they have the potential to produce resins with a bimodal molecular weight distribution. (C) 2001 Elsevier Science B.V. All rights reserved.
