A mathematical model has been developed to predict radial temperature gradients in polymers during dielectric heating. The time‐temperature model includes parameters for rate of dielectric heating, thermal conductivity, density, heat capacity, surface coefficient of heat transfer, and sample radius. The application of this model was checked experimentally on a 2‐in. cylinder of cured polyisoprene.
