## Abstract The number of active centers (__C__~P~) and propagation rate constant (__k__~P~) for ethylene polymerization with homogeneous catalyst LCoCl~2~β+βMAO and supported catalyst LCoCl~2~/SiO~2~β+βAl(__i__βBu)~3~, where L is 2,6β(2,6β(Me)~2~C~6~H~3~Nβ=βCMe)~2~C~5~H~3~N, have been determined u
## Abstract Summary: Method of polymerization inhibition by radioactive carbon monoxide (^14^CO) has been used to determine the number of active centers (__C__~P~) and propagation rate constant (__k__~P~) for ethylene polymerization with homogeneous complex 2,6β(2,6β(Me)~2~C~6~H~3~Nο£ΎCMe)~2~C~5~H~3~
## Abstract Summary: A DFT method has been applied for quantumβchemical calculations of the molecular structure of chargeβneutral complex LFeMe(ΞΌMe)~2~AlMe~2~ which is formed in system LFeMe~2~β+βAlMe~3~ (Lβ=β2,6βbis(imino)pyridyl). Calculations suggested the formation of highly polarized complex L
