✦ Synopsis

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 can be brought about when these materials are extruded. The survey shows that to summarize the results we must consider three distinct ranges of temperature: 1, above about 25 K; 2, between 1 and 25 K; 3, below 1 K. Recent measurements include some further results on extruded polyethylene and the first measurements on liquid crystal polymers.
