Abstract

A composition comprises one or more trimesic acid derivatives of Formula (I)in which R1, R2, and R3 are independently selected from the group consisting of alkyl groups. A polymer composition comprises a composition as described above and a polyolefin polymer. The polymer compositions containing a trimesic acid derivative of Formula (I) exhibit very low haze levels and minimal extraction of the trimesic acid derivative.

First claim

What is claimed is:

1. A compound of Formula (I)

wherein R 1 , R 2 , and R 3 are independently selected from the group consisting of alkyl groups; and each of R 1 , R 2 , and R 3 is in the cis-position relative to the bond to the nitrogen atom attached to the cyclohexanediyl moiety.

2. The compound of claim 1 , wherein R 1 , R 2 , and R 3 are independently selected from the group consisting of C 1 -C 8 alkyl groups.

3. The compound of claim 1 , wherein at least one of R 1 , R 2 , and R 3 is a branched alkyl group.

4. The compound of claim 3 , wherein at least two of R 1 , R 2 , and R 3 are branched alkyl groups.

5. The compound of claim 4 , wherein each of R 1 , R 2 , and R 3 is a branched alkyl group.

6. The compound of claim 1 , wherein the compound is selected from the group consisting of:
N,N,N-tri(cis-4-methylcyclohexyl)-1,3,5-benzenetricarboxamide;
N,N,N-tri(cis-4-n-propylcyclohexyl)-1,3,5-benzenetricarboxamide;
N,N,N-tri(cis-4-isopropylcyclohexyl)-1,3,5-benzenetricarboxamide;
N,N,N-tri(cis-4-n-butylcyclohexyl)-1,3,5-benzenetricarboxamide;
N,N,N-tri(cis-4-isobutylcyclohexyl)-1,3,5-benzenetricarboxamide;
N,N,N-tri(cis-4-tert-butylcyclohexyl)-1,3,5-benzenetricarboxamide;
N,N,N-tri(cis-4-tert-pentylcyclohexyl)-1,3,5-benzenetricarboxamide;
and mixtures thereof.

7. The compound of claim 6 , wherein the compound is N,N,N-tri(cis-4-methylcyclohexyl)-1,3,5-benzenetricarboxamide.

8. The compound of claim 6 , wherein the compound is N,N,N-tri(cis-4-n-propylcyclohexyl)-1,3,5-benzenetricarboxamide.

9. The compound of claim 6 , wherein the compound is N,N,N-tri(cis-4-isopropylcyclohexyl)-1,3,5-benzenetricarboxamide.

10. The compound of claim 6 , wherein the compound is N,N,N-tri(cis-4-n-butylcyclohexyl)-1,3,5-benzenetricarboxamide.

11. The compound of claim 6 , wherein the compound is N,N,N-tri(cis-4-isobutylcyclohexyl)-1,3,5-benzenetricarboxamide.

12. The compound of claim 6 , wherein the compound is N,N,N-tri(cis-4-tert-butylcyclohexyl)-1,3,5-benzenetricarboxamide.

13. The compound of claim 6 , wherein the compound is N,N,N-tri(cis-4-tert-pentylcyclohexyl)-1,3,5-benzenetricarboxamide.

14. A polymer composition comprising:
(a) the compound of claim 1 ; and
(b) a polyolefin polymer.

15. The polymer composition of claim 14 , wherein the polyolefin polymer is a polypropylene polymer.

16. The polymer composition of claim 15 , wherein the polyolefin polymer is selected from the group consisting of polypropylene homopolymers, polypropylene random copolymers, and mixtures thereof.

17. The polymer composition of claim 16 , wherein the polyolefin polymer is a polypropylene random copolymer.

18. The polymer composition of claim 17 , wherein the polypropylene random copolymer contains about 1 to about 7 wt. % of a comonomer selected from the group consisting of ethylene, but-1-ene, and hex-1-ene.

19. The polymer composition of claim 14 , wherein the polymer composition contains about 0.001 wt. % or more of the compound of Formula (I), based on the total weight of the polymer composition.

20. The polymer composition of claim 19 , wherein the polymer composition contains about 0.001 wt. % to about 0.2 wt. % of the compound of Formula (I), based on the total weight of the polymer composition.
