Abstract
The thermal diffusivity of samples of powdered high polymers can be increased (at least in the temperature range 1–20 K) by compressing them with copperpowder. Hence thermal relaxation times in specific heat measurements can be decreased. The specific heat of the copper is relatively small and is well known. Calorimeter vessels are then unnecessary.Keywords
