This work presents the modelling of heat transfer in a polymer sample submitted to a microwave field in the quartz column
of a dilatometer surrounded by vacuum to avoid convection. The temperature rise is studied in transient state by the finite
element method. It is assumed that a uniform and constant heat production is maintained in the entire volume of the sample.
It is shown that it is possible to design the set composed of the sample and of the column to achieve a nearly uniform temperature
in the whole volume of the sample while its temperature is raised from 20 to 250°C at a heating rate of 5 deg·min−1.
