## Abstract Summary: The number of active centers (__C__~P~) and propagation rate constants (__k__~P~) for polymerization of ethylene with supported catalysts LFeCl~2~/SiO~2~, LFeCl~2~/Al~2~O~3~ and LFeCl~2~/MgCl~2~ (Lβ=β2,6β(2,6β(Me)~2~C~6~H~3~Nο£ΎCMe)~2~C~5~H~3~N), activated by an Al(__i__βBu)~3~ c
The immobilization of the soluble precatalysts [(ArN C(Me)) 2 C 5 H 3 N]FeCl 2 , where Ar = 2,4,6-trimethylphenyl (A) or 2,6diisopropylphenyl (B), on supports derived from a spherical MgCl 2 -alcohol adduct yields active supported systems for ethylene polymerization. The activity of the supported ca
## Abstract **Summary:** A wellβdefined flat model of a supported homogeneous polyolefin catalyst is prepared on the basis of an immobilized bis(imino)pyridyl iron complex on a super flat silica surface. The amount of supported catalyst precursor is quantified using XPS. This model catalyst remains
