โฆ Synopsis
The generality of baric changes in static dielectric permeability of polymers for different temperatures of the sample is considered in the present work. It is shown that the initial growth of dielectric permeability is followed by its lowering that arises during the glass transformation of the sample. Formulas that reflect the changes of dielectric permeability under isothermal changes of pressure and isobaric changes of temperature of the sample are obtained.

Through the experimental investigation of solid granule compaction, it is demonstrated that the combined influence of pressure and temperature on the bulk density of solid polymer granules is very significant for all materials, although the effect is different for different materials, especially amo
