Researchers from Institute of Chemistry Describe Findings in Alkenes

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Alkenes is now available. According to news reporting out of Beijing, People's Republic of China, by NewsRx editors, research stated, "2-[1-(2,6-Diisopropylphenylimino)ethyl]-6-[1-(pyren-1-ylimino)ethyl]pyridine (L1) and 2,6-bis[1-(pyren-1-ylimino)ethyl]pyridine (L2) were synthesized and used to prepare the corresponding Fe complexes Fe1 and Fe2 from FeCl2. All new compounds were characterized, and single-crystal XRD analysis of Fe1 was performed."

Our news journalists obtained a quote from the research from the Institute of Chemistry, "The -conjugated pyrenyl substituent enhanced the catalytic activity of the Fe complexes, which display high activity in ethylene polymerization up to 10(7)g(PE)mol(Fe)(-1)h(-1) (PE=polyethylene). These Fe complexes were easily immobilized on multiwalled carbon nanotubes (MWCNTs) through noncovalent - interactions."

According to the news editors, the research concluded: "The supported precatalysts showed better ethylene polymerization activity than their homogeneous counterparts to produce well-dispersed MWCNT/PE composite materials."
