The subject of the invention are coordination compounds of oxovanadium(IV) with the following anions: thiodioctanoate (TDA), iminodioctanoate (IDA), dipicolinate (dipic), diglycolate (ODA), N-methyliminodiacetate (mIDA) and 4,4′-dimethoxy-2,2′-bipyridyl (dmbipy), 1,10-phenanthroline (phen), 2,2′-bipyridyl (bipy) or dimethyl sulphoxide (DMSO) and dioxovanadium(V) coordination compounds containing a dipicolinate anion (dipic) in the coordination sphere and protated molecules of 2-phenylpyridine (2-ppyH) or 2-(4-methylphenyl)pyridine (tpyH) as counterions.
Applications:
- production of polyethylene and its copolymers (including LDPE, HDPE),
- synthesis of functional materials with adjustable molecular weight,
- industrial implementations replacing classic Ziegler–Natta or metallocene catalysts.
Technological advantages of the compounds:
- higher activity with lower complex consumption,resistance to air,
- ability to carry out synthesis reactions in an aqueous environment,
- lower production costs (no precious metals, simple synthesis).
