NMR Study of Branched Polyethylenes Obtained with Combined Fe and Zr Catalysts

摘要: The products obtained with the system {[(ArN=C(Me)) 2 C 5 H 3 N]FeCl }/MAO (Ar = 2-C 6 4 -(Et)) (1) and ones by use of 1 in conjunction Me SiInd ZrCl /MAO (2) or EtInd -ZrCl (31 were completely characterized NMR 13 NMR. Catalyst gives mainly linear α-olefins molecular weights close to 2000 g/mol a low amount alkanes. using only ethylene as monomer branched polyethylene ethyl, butyl, long branches. Some unreacted α-olefin was also found some cases, especially reactions where high ratio Fe Zr used.
