PHOTOLATENT TITANIUM CATALYSTS Russian patent published in 2015 - IPC B01J31/02 B01J31/22 C08G18/22 C09D175/04 C08F4/64 

FIELD: chemistry.

SUBSTANCE: invention refers to Ti-chelate catalytic compound for polyaddition or polycondensation reactions involving catalysing by Lewis acid-like agents. The above catalytic compound contains: (i) 50-99 wt % of at least one compound of formula I and (ii) 1-50 wt % of at least one chelate ligand of formula

.

In formula I, R₁ represents C₁-C₃₀alkyl or C₂-C₃₀alkyl, a chain of which contains one or more unattached O-atoms; Y represents or ; Y₁ represents or ; Y₂ represents or ; Y₃ represents or ; the radical values R₂-R₁₃ for the attachment of formula I and the radical values for compounds of formulas IIa, IIb or IIc are presented in the patent claim. The invention also refers to a polymerised composition and using it, to a method for polymerising the compounds, to a coated substrate and a polymerised or cross-linked composition.

EFFECT: presented invention is producing the Ti-chelate catalytic compound with the prolonged shelf life and good photolatency of the catalyst.
