Abstract
Measurements of thermal conductivity and specific heat carried out on the same samples of extruded semicrystalline polyethylene show that there is no direct relationship between the measured specific heat and the thermal conductivity. Although two-level resonance theory can explain the specific heat it does not explain the thermal conductivity measurements of such semicrystalline materials. Preliminary calculations show good agreement with experiment using the structure scattering theory of Morgan and Smith (1974).Keywords
