STABILISATION OF ORGANIC MATERIAL WITH MANNICH COMPOUNDS BASED ON AMINOTRIAZINE Russian patent published in 2016 - IPC C08K5/3492 C07D251/48 C07D251/70 

FIELD: chemistry.

SUBSTANCE: invention relates to use of one or more aminotriazine-based Mannich compounds of formula (I), and/or their dimers or trimers, and/or one or more of their preliminary condensate of formula (II) as antioxidants for organic materials. In formula (I) and (II)

,

A is O; R⁴ is R⁵-N-R⁶ group, connected to triazine ring with structure (I) or (II) by central nitrogen atom; R¹, R², R³, R⁵ and R⁶ represent hydrogen, or Q¹ or group of formula (III) , R⁷ is hydrogen, where in case of A, equal to O, R⁷ is found once, R⁸ is selected independently from Q¹ or can be group with structure (IV), where R^8′ means R⁸ , n equals to 1 or 2, where n is in ortho-position to AR⁷, Q¹ is selected from group comprising unsubstituted, linear or branched C₁-C₁₈-alkyl, unsubstituted, linear or branched C₂-C₁₂-alkenyl, unsubstituted C₃-C₇-cycloalkyl, unsubstituted C₆-C₁₀-aryl, m ranges from 2 to 20. Invention also relates to Mannich compound based on aminotriazine; methods of organic material stabilization against destruction; to polymer compositions; to use of polymer compositions.

EFFECT: technical result: Mannich compounds are obtained based on aminotriazine, which increase resistance of polymer to oxidative decomposition.
