METAL COMPLEX CATALYSTS AND POLYMERISATION METHODS USING SAME Russian patent published in 2016 - IPC C07F5/00 C08F4/52 C08F4/54 C08F36/06 

FIELD: chemistry.

SUBSTANCE: invention relates to complex of general formula , where M is metal atom of 3rd group or Lanthanides; L is neutral Lewis base; z is an integer from 0 to 3 inclusive; each R² independently denotes H, substituted or unsubstituted hydrocarbon group, radical or heterocyclic compound containing heteroatom functional group; R¹ is halogen atom or R²; each R³ represents group of -N[SiH(R⁴)₂]₂, where each R⁴ is C₁-C₁₀ alkyl group, provided that two groups R² or R¹ and one group R² together with atoms to which each of these groups can form circular structure. When the R¹ or R² is hydrocarbon group, hydrocarbon group can be substituted with halogen atoms, other hydrocarbon groups, heteroatom-containing groups, wherein the above heteroatoms represent O, S, N, B, Al, P, Si, Ge or Sn. Also disclosed polymerisation catalyst composition and method of producing polymer.

EFFECT: complexes can be used in catalytic system for polymerisation of ethylenically unsaturated hydrocarbon monomers.
