Experimental time and temperature dependencies of the complex Young's modulus components have been analyzed for isotropic and uniaxially oriented polymers of different chemical structures. In the regions of relaxation transitions, these dependencies have been described by the equations of viscoelasticity. For highly oriented polymers, the relaxation time distribution has been approximated by a rectangular ('box') function. Such an approximation results specific formulae for time and temperature relaxation of the Young's modulus components.
