With employment of ACM (acrylic rubber) and ENR (epoxidized natural rubber), the rubber and chemical additives were Compounded by mechanical method using a Banbury mixer and an open 2 roll mill. Then rubber vulcanizates were prepared by compression mold, and cure characteristics (cure behavior, scorch time, and optimum cure time), maximum torque value, Mooney viscosity, and dynamic mechanical properties of the test specimens were measured. The torque value of rubber mix was obtained with a maximum at ACM/ENR (=25/75) blend. Results determined from a Rheovibron showed two glass transitions (T(g)) for ACM/ENR (=75/25) indicative of the immiscible nature of the blend. However, in ACM/ENR (=25/75) blend, a single T(g) indicating miscibility was obtained.
