Description	Living/controlled polymerization of hex-1-ene initiated by nickel diimine catalysts of general form [ArN?C (1,8-naphthalenediyl)C?NAr]NiBr2 activated by simple organoaluminium compounds was investigated. Polyhexenes with a very narrow molar mass distribution and molar mass controlled by the monomer/initiator ratio were prepared using diethylaluminiumchloride, ethylaluminiumdichloride and methylaluminiumdichloride as cocatalysts for nickel complexes 1 (Ar?2,6-iPr2C6H3) and2 (Ar?2-tBuC6H4). Nickel complexes with smaller aryl substituents (3, Ar ? 2,6-Me2C6H3; 4 Ar ? 2,4,6-Me3C6H2; 5, Ar ? 2,6-Et2C6H3) undergo transfer reactions significantly. For themost bulkycomplex 1 activated byethylaluminiumdichloride living hex-1-ene polymerization was achieved, proved by the reinitiation of polymer growth upon the addition of fresh monomer. The effect of Al/Ni ratio on the activity of the catalytic systems was studied by dilatometry. The catalytic systems were investigated by UVevis spectrometry and a new interpretation of their absorption spectra was suggested.
