A pulse method for simultaneous determination of the specific heat and the thermal diffusivity of plastics by using double-layer sample "metal-plastics" has been presented. Investigations have been carried out using a sample made of polytetrafluoroethylene (PTFE) of diameter 12 mm with glued molybdenum foil of thickness 0.1 mm. The temperature range of investigations is 290 - 400 K.
