Abstract: The mechanical properties and swelling behavior of n-pentane through acrylonitrile Butadiene Rubber (NBR) with different acrylonitrile content were studied. In addition to the mechanical and the swelling properties, the curing characteristics and crosslink density were also investigated. The vulcanization kinetic parameters were determined using autocatalytic model. The NBR with 33% acrylonitrile content showed the highest the activation energy. The highest crosslink density was obtained from the NBR with acrylonitrile content 28% and the crosslink density effected to its mechanical properties and swelling behavior. The highest crosslink density exhibited the highest hardness, tensile strength, elongation at break values, the better compression set, the lowest equilibrium n-pentane uptake (Q∞) and the Sorption coefficient (S). The Diffusion coefficient (D) increased with decreasing the acrylonitrile content.
