The effective thermal conductivity and the coefficient of linear thermal expansion of crystals fabricated from polymer powders are studied, depending on the content of fine iron. A considerable improvement of the thermal characteristics in the batch of samples fabricated by mixing of the polymer matrix and iron with the following heating and holding at a temperature by 20 K above the melting point of the polymer and further implementation of a crystal structure (by temperature lowering) in the rotating inhomogeneous magnetic field is identified. In this case, an anomalous change of the coefficients of linear thermal expansion of composite depending on the weight of iron added there with amount of less than 5% of the original mass of the pure polymer is detected.

Key words: thermal conductivity, linear thermal expansion, composites, magnetic field.
