Supported metallocene catalysts for polyolefin production : review of the immobilization strategies [PDF]

, 2011
The inadequacy of strategies used for the heterogeneization of metallocene catalysts is pointed out as one of the main causes of the lack of industrial employability of such polymerization catalysts.

Insights into the activation of silica-supported metallocene olefin polymerization catalysts by methylaluminoxane

, 2019
Metallocene-based olefin polymerization catalysts often require large excesses of co-catalyst for optimal catalyst activation. In this work, mechanistic insights into the activation of supported metallocenes by methylaluminoxane as co-catalyst are ...

C-2-symmetric ansa-metallocene catalysts for propene polymerization: Stereoselectivity and enantioselectivity

, 1998
Important similarities between the new homogeneous catalysts for 1-alkene polymerization based on C2-symmetric ansa-metallocenes of the 4th column and their heterogeneous Ziegler–Natta predecessors are unquestionable; in particular, the factors leading ...
