摘要
The experimental temperature and time dependences of real and imaginary components of Young's modulus of isotropic and oriented polymers is analyzed. An attempt to describe them in the region of relaxation transition is undertaken with the help of relaxation spectrometry. For this purpose, the distribution, function for the relaxation times is approximated by a rectangular distribution. As a result, an approximate formula for the description of temperature/time relaxation of Young's modulus in the region of relaxation transition is derived, suitable for both oriented and isotropic polymers.
