Název v původním jazyce

Titanium and Vanadium Catalysts with 2-Hydroxyphenyloxazoline and Oxazine Ligands for Ethylene-Norbornene (co)Polymerization

Popis výsledku v původním jazyce

A series of titanium and vanadium complexes with oxazoline 2-(4,5-dihydro-1,3-oxazol-2-yl)phenol (L1), 2-(4-methyl-4,5-dihydro-1,3-oxazol-2-yl)phenol (L2), and oxazine 2-(5,6-dihydro-4H-1,3-oxazin-2-yl)phenol (L3) ligands were synthesized, and their structures were determined by NMR and MS methods as (L)(2)MtCl(2). The vanadium complexes were found to be highly active in ethylene (7300 kgPE/(molV.h)) and ethylene/norbornene (5300 kgCop/(molV.h)) (co)polymerization. The polyethylene characteristics were melting temperature (123-142 degrees C), crystallinity degree (49-75%), molecular weight (5.7-8.5 x 10(5) g/mol), molecular weight distribution (1.5-2.4). The ethylene-norbornene (E-NB) copolymer characteristics were molecular weight (2.6-0.9 x 10(5) g/mol), molecular weight distribution (1.6-2.2), glass transition temperature (4-62 degrees C), norbornene incorporation (12.3-30.1 mol%) at initial concentration (0.5-1.5 mol/L). The microstructure of E-NB copolymers depends on the catalyst applied with the highest diads content for the (L3)(2)VCl2 and triads for the (L2)(2)VCl2 complexes.
