- Аннотация: A series of bis(phenoxy-imine) (FI) titanium(IV) and zirconium(IV) complexes have 21 been synthesized. The effect of the nature of the activator (MAO, combinations EtnAlCl3-n+Bu2Mg 22 and iBu3Al + [Ph3C]+[B(C6F5)4]-) on the catalytic activity and properties of the resulting polymers was 23 studied. It was found that Ti-Fi complexes despite the nature of the outgoing ligands (Cl or iPrO) in 24 the presence of Al/Mg activators effectively catalyze the polymerization of ethylene (with the for-25 mation of UHMWPE), copolymerization of ethylene with 1-octene (with the formation of ultra-high 26 molecular weight copolymers) and the ternary copolymerization of ethylene, propylene and 5-vi-27 nyl-2-norbornene (with the formation of polyolefin elastomers). It has been shown that Zr-FI com-28 plexes are not activated by these Al/Mg compositions. The resulting UHMWPE can be processed by 29 a solventless method into high-strength and high-modulus oriented films; however, their mechani-30 cal characteristics do not exceed those obtained using MAO
