The charge percolation mechanism and simulation of Ziegler–Natta polymerizations. Part VI. Mechanism of ethylene polymerization by supported chromium oxide [PDF]
Journal of the Serbian Chemical Society, 2007 Despite intensive research over the last 50 years, many questions concerning ethylene polymerization by supported chromium oxide are still unanswered. Hence, the very fundamental issues of this polymerization are discussed in this paper. It is shown that

Aqueous Catalytic Polymerization of Olefins [PDF]
Angewandte Chemie International Edition, 2002 Catalytic conversions in aqueous environments by transition metal complexes have become a well-established field over the past two decades. However, the vast majority of investigations have focussed on small-molecule synthesis. This may appear somewhat surprising as water is a particularly attractive reaction medium, especially for polymerization ...

Photolithographic Olefin Metathesis Polymerization
Journal of the American Chemical Society, 2013 Patterning functional materials is a central challenge across many fields of science. The ability to lithographically fabricate micro- and nanostructures has been one of the most impactful technological breakthroughs of the last century. In part due to the complexity of the chemical processes in photoresists, there is a limited variety of materials ...
