- Аннотация: The coordination chemistry of a new compartmental ligand - 2,6-(bis-CF3-carbinol)-4-tert-butylphenol with Ti(IV) and Zr(IV) has been studied. The structures of Al, Ti and Zr complexeswith the participation of this ligand were established by X-ray diffraction. Upon activation with Et2AlCl or Et3Al2Cl3 and Bu2Mg, Ti(IV) complex exhibited moderate catalytic activity forethylene polymerization. The obtained UHMWPE samples were processed into high-strength (upto 2.7 GPa) and high-modulus (up to 167 GPa) films through solid-phase molding andorientation drawing. The mono- and binuclear Ti(IV) complexes catalyzed the ternarycopolymerization of ethylene, propylene and 5-ethylidene-norbornene. Ter-copolymers with acontent of propylene units up to 36 mol % and 5-EBN up to 8.6 mol% were synthesized with ahigh activity (2.8-6.3 tons of copolymer / mol Ti h); the mechanical characteristics ofelastomeric materials have been studied.
