AN IMPROVED CURE SYSTEM COMPOSITION AND A METHOD FOR CURING CHLORINATED ELASTOMER COMPOSITIONS |
摘要 |
The instant invention is an improved cure system composition and a method for curing chlorinated elastomer compositions. The cure system composition includes a polymercapto crosslinking agent; an inorganic base; and an onium salt. The onium salt has a formula selected from the group consisting of wherein Z is a nitrogen or phosphorous atom, R1 to R4 are independently alkyl or aryl groups containing between 2 and 8 carbon atoms, and the total number of carbon atoms on R1-R4 is between 10 and 14; wherein R5 and R6 are alkyl groups containing between 1 and 8 carbon atoms, and the total number of carbon atoms on R5-R6 being between 5 and 9; and wherein X is an anion. The method for curing a chlorinated elastomer composition according to instant invention includes the following steps: (1) providing a chlorinated elastomer composition; (2) providing a cure system composition as described above; (3) contacting said chlorinated elastomer composition with said cure system composition; and (4) thereby curing said chlorinated elastomer composition. |
