PHOTO-LATENT TITANIUM-OXO-CHELATE CATALYSTS Russian patent published in 2017 - IPC B01J31/02 B01J31/22 C07F7/28 C08G18/22 C09D175/16 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst composition for polyaddition or polycondensation reactions based on titanium-oxo-chelate. Composition contains (i) at least one substance of formula I

,

where R₁ and R₂ and R₃ together with C-atom to which they are bonded, form a phenyl group which can be unsubstituted or substituted with one, two or three C₁-C₄alkyls, OR₁₃ or NR₁₃R₁₄; R₁₀ and R₁₁ and R₁₂ together with C-atom to which they are bonded, form a phenyl group, which can be unsubstituted or substituted with one, two or three C₁-C₄alkyls, OR₁₃ or NR₁₃R₁₄; R₄, R₅, R₆, R₇, R₈, R₉, independently represent hydrogen, halogen or C₁-C₄alkyl; provided that only one from R₄, R₅ and R₆ in a group and only one of R₇, R₈ and R₉ in group can be hydrogen; or R₄, R₅ and R₆ and R₇, R₈ and R₉ together with C-atom, to which they are bonded, form a phenyl group; or R₄ and R₅ and R₇ and R₈ together with C-atom, to which they are bonded, form a cyclohexyl ring; R₁₃ and R₁₄ independently represent C₁-C₄alkyl; (ii) at least one chelate ligand of general formula IIa, IIb or IIc

wherein R₁, R₂ and R₃ independently represent hydrogen, halogen or C₁-C₄alkyl; or R₁ and R₂ and R₃ together with C-atom to which they are bonded, form a phenyl group; R₄, R₅ and R₆ independently represent hydrogen, halogen or C₁-C₄alkyl; or R₄ and R₅ and R₆ together with C-atom to which they are bonded, form a phenyl group. Invention also discloses use of catalyst composition, polymerisable composition, use of polymerisable composition, having a substrate coating, method of polymerising compounds, polymerized or cross-linked composition, catalyst for polyaddition or polycondensation reactions.

EFFECT: invention enables to obtain a catalyst composition based on titanium-oxo-chelate, having high moisture resistance, having long storage life and good photo-latency.
