Аннотация:The catalytic properties of post-metallocene system, based on titanium (+4) complex and zirconium (+4) complex with bis-salicylidenimine fluorine-containing ligand in the polymerization of higher olefins were studied. It was shown that the complex activation by methylalumoxane (MAO), depending upon the synthesis conditions, leads to formation of syndio- and isotactic poly-α-olefins with molecular mass from 0.01*105 to 19.98* 105 and with productivity up to 2217 kg Polymer/mole Ti.
