Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 84127-04-8, C14H15O2P.

The synthesis and olefin polymerization behavior of a series of new phosphine-iminoquinoline iron complexes is described. Upon activation, the iron complexes are highly active for ethylene polymerization, producing low molecular weight (MW) linear polyethylene (PE) with activities up to 108 g of PE/((mol of Fe) h). This activity is comparable to that of the most active bis(imino)pyridine iron catalysts and heterogeneous Ziegler-Natta catalysts. The MWs and molecular weight distributions (MWDs) of the resulting polymers can be controlled by the modification of the catalyst structures. In addition, upon activation the iron complexes are capable of copolymerizing ethylene with 1-octene, giving copolymers with alpha-olefin incorporation up to 8.8%.
