First claim
Opening claim text (preview).
The invention claimed is: 1. A composition (AB), comprising: a cyclopentadiene compound (B), and a compound (A) of structure (I): wherein R 1 and R 2 are each tert-butyl; and R 3 is —CN, —O—R 10 , or —R 12 , where R 10 is methyl, ethyl, n-propyl, iso-propyl, n-butyl, n-pentyl, or n-hexyl and R 12 is 2-furyl, 3-furyl, or phenyl. 2. The composition (AB) according to claim 1 , wherein the cyclopentadiene compound (B) is at least one selected from the group consisting of cyclopentadiene, dicyclopentadiene, alkylated cyclopentadiene and alkylated dicyclopentadiene. 3. The composition (AB) according to claim 1 , wherein the cyclopentadiene compound (B) is at least one of cyclopentadiene and dicyclopentadiene. 4. The composition (AB) according to claim 1 , wherein a concentration of the compound (A) of structure (I) is between 10 ppb (m/m) and 100,000 ppm (m/m), based on a total weight of the cyclopentadiene compound (B). 5. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —O—R 10 , where R 10 is methyl. 6. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —O—R 10 , where R 10 is ethyl. 7. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —O—R 10 , where R 10 is n-propyl. 8. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —O—R 10 , where R 10 is iso-propyl. 9. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —O—R 10 , where R 10 is n-butyl. 10. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —O—R 10 , where R 10 is n-pentyl. 11. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —O—R 10 , where R 10 is n-hexyl. 12. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —R 12 , where R 12 is 2-furyl. 13. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —R 12 , where R 12 is 3-furyl. 14. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —R 12 , where R 12 is phenyl. 15. The composition (AB) according to claim 1 , wherein, in the structure (I), R 3 is —CN.
