Recent developments in metal-catalyzed living radical polymerization
This review presents a short overview of recent developments in metal-catalyzed living radical polymerization, mainly focusing on our recent research studies related to the subject. Metal-catalyzed living radical polymerization or atom transfer radical polymerization, which was originally developed via evolution of the metal-catalyzed Kharasch or atom transfer radical addition to chain-growth p...
متن کاملPolymerization of sterically hindered a-olefins with single-site group 4 metal catalyst precursors
A variety of group 4 metal catalytic systems (C2-symmetric {EBTHI}-, {SBI}-type zirconocene complexes (C2-1–4); C1-symmetric (C1-5–8) and Cs-symmetric (Cs-9) {Cp/Flu}-type zirconocene complexes; Cp*2ZrCl2 (Cp* 2-10)), half-metallocene complexes (CpTiCl3, HM-11), constrained-geometry (CGC-12) titanium catalysts) and post-metallocene catalysts (Dow’s ortho-metallated amido-pyridino hafnium comple...

متن کاملCoordination (co)polymerization of olefins
Introduction Middle 1950s may be treated as the beginning of the age of plastics – their global production in last 60 years have increased from approx. 1.5 mln to almost 290 mln tons. The dominating position in production and consumption of these materials for many years has been occupied by polyolefins (in Europe 48% from 57 mln tons of plastics) [1]. Forecasters predict that in coming years t...
متن کاملAqueous Catalytic Polymerization of Olefins
Aqueous catalytic polymerization may seem like a contradiction at first sight. The high water sensitivity of Ziegler or Phillips catalysts applied commercially for the production of polyolefins is well known. However, water offers a unique combination of properties as a medium for polymerization reactions: A high heat capacity, which enables an effective transfer of the heat of polymerization. ...
