Methods of thermal conductivity measurement of high polymers are reviewed critically and a method devised by one of the authors is described somewhat in detail. Necessity of material standards for the measurement is also asserted.
The investigations of the thermal conductivities of amorphous polymers including space network polymers and of semi-crystalline polymers in the temperature range from room temperature to their softening or melting point are summarized. The temperature dependence and some relationships, such as the change of temperature dependence of the conductivity around glass transition vs. glass transition temperature, the conductivity vs. crosslinking density, are described.
