    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 a quaternary ammonium salt. The quaternary ammonium salt has a formula selected from the group consisting of wherein R1 is an alkyl or aryl group containing between 4 and 12 carbon atoms; wherein R2 and R3 are independently alkyl or aryl groups containing between 1 and 8 carbon atoms; wherein the total number of carbon atoms on R2 and R3 are between 3 and 9; wherein R4 and R5 are methyl groups, and R6 is an alkyl group containing between 2 and 8 carbon atoms; 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.

    摘要: The invention provides compositions comprising nitrogen containing chelating agents, which can be used to reduce the effects of zinc contamination on the vulcanization rates of polymercapto based cure systems for halogenated elastomers. Such chelating agents are effective at eliminating vulcanization rate inconsistencies due to zinc contamination, without inducing negative changes to the vulcanization reaction or the subsequent physical properties of the halogenated elastomer vulcanizate. The invention also provides methods of curing a halogenated elastomer using the inventive compositions, and for articles prepared from the same.
