Ti(IV) Complexes with OSSO-Type Diol Ligands as Catalysts for Synthesis of Ultrahigh-Molecular-Weight Polyethylene and Ethylene–Propylene Copolymers
A series of novel complexes of titanium(IV) with OSSO-type ligands were synthesized. In the presence of Al/Mg activators such as {Et2AlCl+Bu2Mg} and {Et3Al2Cl3+Bu2Mg}, all the synthezed compounds catalyzed the polymerization of ethylene (with activity up to 2554 kgPE molM–1 h–1 atm–1). The otained ultrahigh-molecular-weight polyethylene (UHMWPE) samples had a molecular weight up to 7.6×106 Da and exhibited high melting points (up to 143°C) and high crystallinity (up to 84%). It was demonstrated that these polymers can be processed by a solvent-free method into high-strength/high-modulus oriented films (with breaking strength up to 2.2 hPa and elastic modulus up to 127.7 hPa). The synthesized compounds further manifested themselves as efficient pre-catalysts (as indicated by their catalytic activity up to 408 kgcopolymer molM–1 h–1 atm–1) for the preparation of ethylene–propylene copolymers with high propylene incorporation (up to 37%).
期刊介绍:
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
