Abstract
AbstractDynamic vulcanizates were produced from hydrogenated nitrile rubber (HNBR) and three different oil‐resistant elastomers. These are polychloroprene (CR), expoxidized natural rubber (EIR), and carboxylated nitrile rubber (XNBR). These elastomers are dispersed and crosslinked during mixing with HNBR. These dynamic vulcanizates all have an HNBR continuous phase. The HNBR matrix is subsequently crosslinked. Stress–strain measurements in tension and tear resistance were measured on the crosslinked dynamic vulcanizates as well as on cured HNBR, CR, EIR, and XNBR. Measurements were also made following hot air and oil aging. Following aging, the dynamic vulcanizates retain a significant amount of their properties due to the presence of the HNBR matrix. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 95: 2–5, 2005
