    Abstract

    The Monsanto oscillating disk rheometer is shown to be an instrument which quickly and precisely determines the dynamic properties, curing, and processing characteristics of elastomers during the entire curing cycle. Measurements with the rheometer are shown to correlate with measurements made by the more conventional methods. For example, interpretation of the rheometer chart of modulus versus cure time gives results which correlate well with Mooney scorch, Mooney viscosity, and tensile moduli of individual press cures. In addition, dynamic moduli measurements with the rheometer are shown to agree with heat buildup and dynamic moduli measurements made on a conventional dynamic moduli tester. Other uses and the design of the rheometer are briefly described.
