The kinetic features of ethylene polymerization with six methylaluminoxane-activated bis(phenoxyimine) complexes of titanium chloride that are distinguished by the electronic properties of substituents in the phenoxy group are studied in the temperature range 30-80A degrees C and at an ethylene pressure of 0.3 MPa. It is shown that, in the presence of an electro-donor or electron-acceptor substituent in the phenoxy group, the catalytic systems under study exhibit high activity (up to similar to 700 t(PE) mol (cat) (-1) mol (ethylene) (-1) h(-1)) and form high-molecular-mass PE samples (M (eta) = (500-900) x 10(3)) with different molecular-mass distributions. In the case of titanium bis(phenoxyimine) complexes containing donor substituents at the para position of the phenoxy group, the polymerization of ethylene follows the living-chain mechanism, while the introduction of acceptor substituents diminishes the contribution of this mechanism to the reaction.
