AI Technical Summary
⚠Technical Problem
Existing triamide compounds cannot simultaneously achieve low fogging and low extraction in polyolefin polymers, limiting their use in food contact and medical applications.
⚗Method used
By using a trimellitic acid derivative with a specific structure as a clarifying agent and combining it with a polyolefin polymer, the proportion of trimellitic acid derivative in the composition and the preparation method are optimized by controlling the alkyl structure and configuration of the R1, R2 and R3 groups, thereby reducing haze and extraction.
🎯Benefits of technology
A balance between low haze and low extraction is achieved in polyolefin polymers, expanding their applicability in food contact and medical applications.

Abstract
The present invention relates to a composition comprising one or more trimesic acid derivatives of formula (I) wherein R 1 , R 2 and R 3 are independently selected from alkyl. The present invention relates to a polymer composition comprising the composition as described above and a polyolefin polymer. The polymer composition containing the trimesic acid derivatives of formula (I) exhibits very low haze levels and little leaching of the trimesic acid derivatives.(I)
