First claim
Opening claim text (preview).
The invention claimed is: 1. An elastomeric article comprising: a rubber component comprising polyisoprene, and an aldehyde aniline condensate, wherein the elastomeric article comprises less than 1 ppm diisopropyl xanthogen polysulfide residue. 2. The elastomeric article of claim 1 , wherein the elastomeric article meets a minimum requirement of 24 MPa when measured according to ASTM 3577-09 for natural rubber surgical gloves before aging. 3. The elastomeric article of claim 1 , wherein the elastomeric article meets a minimum requirement of 18 MPa when measured according to ASTM 3577-09 for natural rubber surgical gloves after aging. 4. The elastomeric article of claim 1 , wherein the elastomeric article meets a minimum requirement of 17 MPa when measured according to ASTM 3577-09 for synthetic rubber surgical gloves before aging. 5. The elastomeric article of claim 1 , wherein the elastomeric article meets a minimum requirement of 12 MPa when measured according to ASTM 3577-09 for synthetic rubber surgical gloves after aging. 6. The elastomeric article of claim 1 , wherein the elastomeric article is free of dithiocarbamates, thiurams, thiazoles, guanidines, and thioureas. 7. The elastomeric article of claim 1 , wherein the elastomeric article is free of diisopropyl xanthogen polysulfide residue. 8. The elastomeric article of claim 1 , further comprising sulfur. 9. The elastomeric article of claim 1 , wherein the polyisoprene comprises natural polyisoprene. 10. The elastomeric article of claim 1 , wherein the polyisoprene comprises synthetic polyisoprene. 11. The elastomeric article of claim 1 , wherein the aldehyde aniline is selected from the group consisting of butyraldehyde-aniline, heptaldehyde-aniline, and a combination thereof. 12. The elastomeric article of claim 11 , wherein the aldehyde aniline is heptaldehyde-aniline. 13. The elastomeric article of claim 1 , wherein the elastomeric article is free of additional xanthate compounds. 14. The elastomeric article of claim 1 , wherein the elastomeric article is free of additional compounds that function as accelerators for vulcanizing elastomers. 15. The elastomeric article of claim 1 , wherein the elastomeric article is chlorinated. 16. The elastomeric article of claim 1 , wherein the elastomeric article is selected from the group consisting of gloves, probe covers, finger cots, catheters, dental dams, and condoms. 17. The elastomeric article of claim 16 , wherein the elastomeric article is a glove. 18. The elastomeric article of claim 1 , wherein the elastomeric article is powder free. 19. The elastomeric article of claim 1 , wherein the elastomeric article is lubricated. 20. The elastomeric article of claim 1 , wherein the elastomeric article comprises between about 0.05 and 0.5 phr of the aldehyde aniline condensate.
