Journal ArticleDOI
Advances in non-metallocene olefin polymerization catalysis.
TL;DR: The graph below shows the progression of monoanionic and non-monoanionic ligands through the history of synthesis, as well as some of the properties that have been identified since the discovery of R-Diimine.
Journal ArticleDOI
Polymerization of Lactide with Zinc and Magnesium β-Diiminate Complexes: Stereocontrol and Mechanism
Bradley M. Chamberlain,Ming Cheng,David Roger Moore,Tina M. Ovitt,Emil B. Lobkovsky,Geoffrey W. Coates +5 more
TL;DR: The substituents on the beta-diiminate ligand exert a significant influence upon the course of the polymerizations, affecting both the degree of stereoselectivity and the rate of polymerization.
Journal ArticleDOI
Discrete Metal-Based Catalysts for the Copolymerization of CO2 and Epoxides: Discovery, Reactivity, Optimization, and Mechanism
TL;DR: Well-defined catalysts for epoxide-CO(2) copolymerization and related reactions are reviewed here.
Journal ArticleDOI
Agostic interactions in transition metal compounds
TL;DR: The impact of agostic interactions (i.e., 3-center–2-electron MHC bonds) on the structures and reactivity of organotransition metal compounds is reviewed.
Journal ArticleDOI
Catalytic Production of Olefin Block Copolymers via Chain Shuttling Polymerization
TL;DR: A catalytic system that produces olefin block copolymers with alternating semicrystalline and amorphous segments by varying the ratio of α-olefin to ethylene in the two types of blocks is reported, which maintains excellent elastomeric properties at high temperatures.

Journal ArticleDOI
Stereospecific Olefin Polymerization with Chiral Metallocene Catalysts
TL;DR: In contrast to heterogeneous Ziegler-Natta catalysts, homogeneous metallocene-based catalysts as discussed by the authors allow efficient control of regio-and stereoregularities, molecular weights and molecular weight distributions, and comonomer incorporation.
Journal ArticleDOI
The Search for New-Generation Olefin Polymerization Catalysts: Life beyond Metallocenes.
TL;DR: Even late transition metal complexes function as active and selective catalysts for α-olefin polymerization, and an intense search has developed for new-generation catalysts, in both academic and industrial research laboratories.
