This Paper is a review of the factors that determine the thermal conductivity of polymers below 100 K. Starting from the 'universal' behaviour found in all amorphous solids we shall examine how far this can be changed when we come to consider semicrystalline polymers, and the further changes that ca

The thermal conductivity of polyethylene is linear in temperature from -0. 6 K to below 0.03 K. This behavior can be explained by the scattering of thermal phonons of wavelength A from the lamella of thickness H when H < A.

Thermal conductivity of polyamide-imide Torlon 4203 was measured at temperatures between 0.1K and IK. The measurements were carried out in a dilution refrigerator using a steady state technique. The fit on the data gave a temperature dependence of the conductivity: k = c~ โ€ข T ~, with n = 2.23 :t: 0
