TRISAMIDE COMPOUNDS AND COMPOSITIONS CONTAINING THEM Russian patent published in 2024 - IPC C07C233/65 C07C237/38 C08K5/20 C08L23/14 

FIELD: chemistry.

SUBSTANCE: invention relates to a composition for addition to a thermoplastic polymer. Composition contains one or more derivatives of trimesic acid of formula (I), wherein R¹, R² and R³ are independently selected from a group consisting of C₁-C₅ alkyl groups. 70 % or more of groups R¹, R² and R³ of derivatives of trimesic acid of formula (I), which are present in the composition, are in the cis-position relative to the bond with the nitrogen atom attached to the cyclohexanediyl fragment. Invention also relates to a polymer composition for producing thermoplastic articles, containing (a) said composition and (b) a polyolefin polymer.

EFFECT: polymer compositions containing trimesic acid derivatives of formula (I) exhibit very low levels of turbidity and minimal release of the trimesic acid derivative from the polyolefin polymer.
