Abstract A procedure is described for determining the temperature of polymers during electron beam irradiation at high dose rates by measurement of the soluble fractions of samples after various doses of radiation. The soluble fraction data are analyzed to derive values of the crosslinking yield, G(X), at different times, which are compared with the G(X) values obtained for irradiation at various temperatures at lower dose rates, e.g., with 7-radiation, when the temperature is controlled and remains constant. The technique is demonstrated for bisphenol-A polysulfone, which is suggested as a standard reference that can be used to provide an estimation of the temperature rise in other polymers with similar dimensions during electron beam irradiation at high dose rates. Low dose-rate electron beam irradiation (3 Mrad/h) has been shown to give the same G values as “Co 7-irradiation (0.1 MGy/h) under the experimental conditions.
